BSC SECOND SEMESTER II COMPLETE PHYSICS II YAHI SE AAYEGA EXAM II 75/75 CONFIRMED ✅

Added: 2026-05-12

[00:02:22]Good evening. Good evening. Good evening to Everyone. Mi Audible and not quickly Please confirm. Let's start then Session.

[00:02:33]Sir I am in Physics minor and the class What should I do with it? in your math class So it is a lot of fun. Absolutely very good.

[00:02:39]If your minor is my brother then the minor's Your exam is in the first and third semester.

[00:02:44]There is an exam. Then your minor exam.

[00:02:45]Will not done. Ok? If the university's I don't know, but what we have here There is a university locally, this is the rule there.

[00:02:50]Is. Ok? Okay, no problem. So Jin People have exams, they should be serious and good.

[00:02:55]Get started with it. Ok? starter I'm going to the session and as much as I can Please share the link. so hello everybody this Your brother and dear friends, today we are Finnish Will do complete Physics paper in which Andar Hum Sare Top M Kitna 75 MCQs Must be covering it here. Before this I have given you both the books, whether it is Book One, Book to be. The concept is provided Already. But as we already Be it mathematics or physics, whenever we While solving, he explains the concept along with it.

[00:03:21]Let's move on, dear friends. So copy pen Take it and sit down. Everything Concept Detailed I will go on explaining here and We will continue solving the questions. Correct Is? Let's go. Let go Ok. So first of all today I will present the PPT to you.

[00:03:33]I have prepared it and brought it in front of you. It took a lot of time In making this into a PPT. So this PPT Send it to you on your Telegram channel along with the solution.

[00:03:39]Will be given. What is in a PDF? Only The question paper goes to you. Ok?

[00:03:42]Now the solution has also been provided to you.

[00:03:44]I will go, dear friends. Ok? Let's go then First question in front of your screen Is. First question: what are you saying to me?

[00:03:50]that one of the most efficient engines over Develop operate between first one own one An engine is provided which can generate 2100 Kelvin and Works between 700 Kelvin. Babu who My brother, he has high temperature, we What is the temperature of the source?

[00:04:05]2100 Kelvin and the lower temperature was There used to be the temperature of the sink, which we used to call are 700 Kelvin. And this engine The efficiency will be 1 - t2 / t1. Remember The formula for direct efficiency was also asked.

[00:04:16]It goes to you like a carnod engine Efficiency of refrigerator It may be okay, this is also asked to us now.

[00:04:22]- t2 how much do I have that's my brother 700 and this is what I have 2100 cut three Time will come to you 1/3 - 2/3 Multiply it by 100, my brother, three If you subtract this from 33.33, you will get 33.33 And from here it will come to 66.66%, this percentage I agreed to you. He asked what is it? Ahead Read this carefully to see if it actually If efficiency is 40% then what percentage of Its maximum possible efficiency? So its What will be the maximum possible efficiency?

[00:04:53]Whereas if its actual efficiency is 40% So see how to remove this? Its The formula will be Babu 40/66 and multiply Make it 100%. When you solve it So whatever answer comes near about this will come 60%. Ok? Actual frequency and You took it out and multiplied it by 100.

[00:05:11]I will get an answer which is near about How much will it cost? 60% are all my brothers The questions are not lengthy. don't worry just Only a few of the result based questions There are questions. I can't see it sir Question quality is not visible.

[00:05:22]I don't see a good question.

[00:05:24]Brother. Hey man, this is a mistake in this PPT.

[00:05:27]Is. Can you see the question now? Now Look, here is your question and the solution.

[00:05:31]There you have it, and you have the answer.

[00:05:33]It is made. You have scored 60% in the answer to this.

[00:05:37]What was your answer, Babu? 60% is it Clear and Not Now Visible Self Study with G Good evening Sir Ji. very good Evening brother. Pankaj, today class after a long time I did not see it. Puneet Thakur Yes. Ok.

[00:05:52]Yes, I have zoomed it. Sir, show me the question No. Now there is no problem anymore No. Sir, my exam is on 15th. don't This is probably MSU's paper.

[00:06:00]It is the same paper. Look ahead to these producing Cooling by adiabatic diamagnetic V Have you used this? What is it telling you next?

[00:06:07]I will see if the Hindi one is also from here.

[00:06:08]I will give you the Hindi speaking children.

[00:06:10]What is written in both of them, oh Baba, it's okay.

[00:06:13]These are producing cooling cooling By whom to buy when produced adiabatic diamagnetic we have use we If you use it, what kind of substance or What kind of substance do we use?

[00:06:24]What is a paramagnetic called?

[00:06:26]What kind of substance is your paramagnetic substance?

[00:06:28]I use it my dear brother Paramagnetic Substances Quick Answers Everyone please comment on this in the comment box.

[00:06:33]Remember the question written below.

[00:06:35]A short video was provided to you I provided the top boss trick.

[00:06:38]Laga Top vs Boss Top vs Boss Top Versus Boss my brother Top Boss Top Boss remember Is it coming or not, oh I am remembering you If it is not coming then you can ask the top boss Tell me quickly which of these is Maxwell Which of the following is not an equation?

[00:06:52]Remember, Maxwell's equations are not I had written the trick for you, you will tell me Brother, please tell me again, please please please Player okay here I'll write top here I will write it here, boss. Hey, go away friend.

[00:07:02]Why are you showing poverty?

[00:07:05]Top and Boss. Top and Boss. A relation like this There was a relation like this, there was a relation like this And by doing a relation like this 1 4 3 2 There were relations nearby. There was first, there was fourth. These Were negative. Now look carefully. Now you are 1 Watching the minutes. What is the fourth relation which I have it? ds will become over dsdp. So dvp / dt will come. dv/dt is coming. any problem Not there. Ok?

[00:07:31]Here is p. p should be a constant here.

[00:07:33]Ok? A p is a t such that p and t and v Let's see. t and v is formed by dt over and dt over sorry dt / dp dt / dp so aise Let's move dt / dp and put dv over dx.

[00:07:50]And then if the first one is already checked Will give. See where the temperature and pressure are.

[00:07:55]We have? The temperature is like this and we have to walk like this No then it means delt over, good det over D is coming down Dt over Dd first then Delp overs first negative is correct The first one is correct my brother, second check do ds over ds over dv ds o dv like this will run and will be equal to dp / dt this is also correct Yes my brother, I will check it with myself again.

[00:08:20]relation with dt / dp dt dt / dp dt / dp and dt / dp and dvp over d this is also right my brother came again I have the last one and these are negative.

[00:08:35]Both are negative, there is no negative sign in it.

[00:08:38]That is why it went very wrong.

[00:08:39]I turned it around, friend, I had to use my brain so much.

[00:08:41]Look what's coming your way This DSP is right, DV overt is also right.

[00:08:46]Hey brother, this was the fourth relation, who is this?

[00:08:48]This relation was the fourth equation, which was formed like this ds overdp look carefully then what will be created dv Over dt okay brother. Then look at the temperature here.

[00:08:56]Constant here pressure constant but here Negative sign comes. It is not given in this.

[00:08:59]That is why it went wrong with me.

[00:09:01]Ok? What has happened to us? wrong It is done.

[00:09:06]Everything went well. very good. B of three They are saying, Sir, where did you study such a good thing?

[00:09:16]Shall we take it sir? Which one would come immediately? Oh no!

[00:09:17]My brother. For all universities you can apply for any You should also be from the university. All universities And all university papers are here Will be solved. This time MGPRO and Guru Jambeshwar University paper late Is. MSU students have their paper early.

[00:09:28]Their paper solution is being done here.

[00:09:29]But you will see when I give you this paper Solved as many as other universities The children also saw the mathematics paper.

[00:09:34]It was very beneficial for everyone.

[00:09:35]Was. So it will be very important for all of you.

[00:09:37]Ok? Whether you are DDA, MGPR, Be it CCS or whatever names you are writing It is for everyone. Ok?

[00:09:44]Yes. Ok. Let's see the number of students who liked it.

[00:09:48]Not done. Everyone please like Give it to me brother. in isothermal isobaric Process. Now here only isothermal Would. Understand my brother? if only If it were isothermal, then my brother would be in isothermal The temperature is constant. at temperature Depends on the internal temperature Energy. If Babu is an isothermal process, right?

[00:10:08]So the internal energy will remain constant. But If you have process isothermal Isobaric means both isothermal and isobaric Then brother, the constant that remains in it The name of the thermodynamical function is Gibbs Free Energy Notes to my points Divide the Gibbs free energy into isobaric The pressure is constant in isothermal The temperature is constant and the temperature Depends on your internal energy MGPRU has come in the exam Bhujeshwar University CCSU All in A question has come which I will address separately.

[00:10:40]You are fine, concept is clear, done, okay?

[00:10:47]Oh no! my dear friend yes okay okay hey friend let's go okay We will see ahead, we will see ahead, no no friend Let's see ahead, my brother, come forward.

[00:11:01]Come, come, what is he saying, the frequency of N heart play oscillator brother now I am using this You tell me about this, I will tell you brother, this one Which hand is it, tell me brother, this is the right train.

[00:11:10]Left. Now brother, I will drive it here.

[00:11:11]I am not going to get it done. Its result is 1/ 2π l1l2 + 2l okay? into C is into C My brother. This is the formula I have.

[00:11:21]Heart of CRO. CrO is cathode ray Oscilloscope.

[00:11:26]Cathode Ray Oscilloscope.

[00:11:30]oscilloscope And its heart, its heartbeat, The one who has a heart has a name.

[00:11:36]CR-T cathode ray tube. Which answer will come Baboo? Cathode ray tube. Heart of CRO It is a cathode ray tube. You can get it medically Use in the field. You must have seen An apparatus of this type is Next to this, it is installed here near us.

[00:11:51]You saw this in the tube when the patient was lying there.

[00:11:53]It happens. You must have seen this in movies.

[00:11:55]TV screen and climbing here Beats up. And then go on like this, Take this brother. End of story. Then the screen But it shows our signal near you, right?

[00:12:04]Babu, who shows that heartbeat? They CRO is a cathode ray oscillator My brother, I am telling you so many things now.

[00:12:10]Didi, you are not going to forget this, okay, okay done.

[00:12:13]Now move to another point Come on, come on Yes, look at this, if I take this here I tick this red one again.

[00:12:22]It is written that CRO will come, look he has come brother.

[00:12:26]Brother Move ahead, move ahead, friend, zoom in, zoom out Something went wrong, otherwise I will give you the session along with it.

[00:12:33]I would have sent the PDF, no problem.

[00:12:35]All my brothers and sisters can watch it live here.

[00:12:37]Are you all enjoying the concept or If you are not able to do so, please write it in the comment.

[00:12:40]Brother, are you understanding everything or not?

[00:12:41]remained. CRO is used to measure CRO What is used to measure? So Voltage Frequency Fuzz Voltage Near frequency fuzz. Ok? Good Junction resistance in reverse biasing It happens. Now hey brother I am reverse biasing What should I talk about? So what did you do? reverse What did you do in reverse biasing?

[00:12:59]confirmed that you had a PN junction diode And what did you do with that PN junction diode?

[00:13:03]Did? His poor poor guy's P terminal You had it, this happened to us.

[00:13:09]Potential Barring. Its P terminal from the negative and the other terminal from the positive Gave. So the current is the majority from its hole Charge is carrying, he started running here Given. The electrons start running here Given. Did any current pass through the junction? No.

[00:13:24]Very little current flows through it. You You will see that its graph looks something like this. These So that's the graph with forward devising.

[00:13:29]But reverse by the slowly slowly slowly It is not increasing. It is not increasing. right away It increases. Suddenly you have a breakdown In that case there is very little current In starting. And when the current is very low Babu, resistance is always high. So Its measurement will be done in mega ohms.

[00:13:44]goes. Do I have a mega ohm somewhere?

[00:13:46]Are you writing? Do I have it somewhere?

[00:13:48]Babu, don't read Om. These Mega Om It is written my brother. What is written?

[00:13:52]Mega ohms. Resistance Measure in Mega Ohms is done. That is why because its There is very little current inside, my brother. Its The current inside is very low.

[00:14:06]Hey friend, no, I am saying one thing brother sir, you Chanak ke gataar ho Dude, look at this download, let me tell you my There's nothing like that from the side, I don't know of.

[00:14:15]Where is the download option provided?

[00:14:16]It is not given from anywhere, okay, I I will try you if this happens from somewhere today I feel like this after watching news videos etc. If I find something, I will download it.

[00:14:22]I will make it available to you, don't worry, it's okay.

[00:14:25]King of Physics my favorite Guru ji thank you you love you my brother love you my brother okay Let go Let go Now let's look ahead, forward, forward, forward Brother, we will come to you, move ahead, move ahead Go ahead, go ahead, look again, hey brother, what The friend is doing zoom zoom zoom equal zoom zoom Now listen carefully to what we have.

[00:14:49]What we have is an NPA.

[00:14:51]Transistor is preferred to PNP Location of transistors NPA transistors But you are giving preference to PNP like When someone has work to do at home Preference is given to the eldest The younger one thinks that brother should go everywhere.

[00:15:05]I am told by my brother that I have no preference.

[00:15:07]No, but it is available. not given priority She goes. But love the little one Much is done. Ok? Something No, it's okay. But what about here Are you speaking my brother? that NPN Transistors are used for At the place? In place of PNP. What does it mean NPN transistor is good. Why butt?

[00:15:22]Is it okay my brother? Because in NPN there are two Bar Aya N. and majority charge within N Electrons are carriers. And The electron moves very fast.

[00:15:30]Baboo. And the faster you run The more mobility there will be in him. His The greater the conductivity, the greater its The better the conductor, the better the conductivity Will make. This will work. That's why here NPN transistors are preferred Is. In whose place? of the PAP. it has Higher mobility for electrons than not in PAP transistor. which is PAP Transistors do not have it themselves.

[00:15:53]In a PNP transistor, the majority of Yes, those are holes, Babu. and holes Mobility is not as much as It has more electrons. That's why Whenever we make a circuit, whether we Who are you talking about? We had read a RC coupled amplifier there we Transistor NPN used. any other If we make an electronic circuit, there But we use NPN transistor in Place of PAP transistor. cleared Didn't it happen my brothers? It became clear that Didn't it happen? Ok? Janta Janardhan friend here But it should be more, only then will it be fun. Yes Whatever your university may be, I have asked you I have already told all the universities It is the most welcome class. Plenty for everyone This is a very useful class, my brother. Ok?

[00:16:33]But no matter how many people are new in the session If you come, please subscribe brother.

[00:16:36]to do. Ok? Yes, only then will it be fun. Zoom. Oho Friends, how much zoom will you guys get? Sir this How do you make physics so easy?

[00:16:46]Ok.

[00:16:48]Hey, I told you about Zoom, my brother. The zoom itself So I told you my brother. And how much of this you Take it and tell me. Ok? So your answer to the first one It will have higher mobility for electrons Then not in PNP transistor. You read here Can PA & PAP transistors than Holes. Ok? compared to whom In? than Holes. of electron Mobility is high. and electrons Which one has more? that in mpn There are. That's why we give preference to NPA We give. What do the children do now? Whose The answer is all of these. who did not read So you will apply all of the all and it will be wrong.

[00:17:17]Ok? It will be wrong. for transistor the Current relation between CBC means There is a common base. Now there are three modes brother.

[00:17:24]We can define a transistor as having an output and There are three ways to apply common inputs: Are. keeping its base common, its conductor By keeping it common and its ammeter common.

[00:17:32]There are three terminals. base, ammeter, Collector. The biggest one is the collector. from him The ammeter is small. is the smallest Base. The most common doping is We have it near the ammeter. Near Ammeters carry charge in themselves But the big collector is made Because the current that enters is from the ammeter Therefore, the largest current ammeter The big terminal is the collector, my brother.

[00:17:53]Okay, now come over here to us.

[00:17:54]I will give you only two of the three formulas.

[00:17:56]The most commonly used formulas are The formula for alpha and beta is alpha Current gain in CB mode and beta What is the current gain in oven ammeter mode?

[00:18:04]Brother, I have the formula for alpha.

[00:18:06]Pass beta / 1 + beta and formula of beta My brother is Alpha / 1 - Alpha Beta Beta is always much greater than one.

[00:18:15]Alpha is always less than one. Alpha Babu, who is younger than me? from one It is small. It is bigger than one. So look Beta equals this simple first formula It's becoming beta equal to if I'm here If I subtract it from this, I get alpha / 1 - alpha.

[00:18:27]Meaning the first option is my right. Both relations You can remember. Alpha is always the current Sorry, the current gain of common base mode It is always smaller than one and in common emitter mode.

[00:18:37]The current gain is always the same More. We will remember the formula of current gain.

[00:18:41]Always output current is above input current.

[00:18:43]The output current is the input current.

[00:18:45]Brother. Ok? Let's go. Ok? now look now You have been given a question. Anything It is not there but it is nothing, right? Now You will say brother, how is there nothing like this? You They say anything. Ok? We are afraid Looks like physics. Hey, don't be afraid brother.

[00:18:58]I will make you fall in love with physics. Don't worry.

[00:18:59]I will make you memorize all the formulas. of tricks I will remind you as well. no need to be afraid Not there. Both tricks and concepts We will keep it inside him. Ok?

[00:19:06]Let's move ahead now. Let's move ahead.

[00:19:08]Look, let me give you some formulas here.

[00:19:11]If you take it out, you promise very well.

[00:19:13]I will write it down and keep it in my copy. Ok? Now here But we will write IE which means ammeter.

[00:19:18]Current. Beta, I have given you this much. IB to you I have given this much. So what are you going to ask?

[00:19:22]Brother? Well sorry IE is the only one asking. Good Ok. Ok. Ok. Now listen carefully From. Now listen my brother.

[00:19:28]I have the formula for beta, for alpha formula and gamma formula all three work Of. I did not see any of the three in the paper.

[00:19:35]Can. Alpha, Beta and gamma are alpha current gain in Common base mode. And in common base mode, if this If current gain is there then brother output current up The input is the common base. So the base current is She will not come. Who is left? collector current and Ammeter current. So this is its formula IC/IE. Now you will say why did you say IC/I only You? Let's assume that you have the base current.

[00:19:58]If not, then two are left. Now in two it means You can take any ratio. No I said alpha is less than one. from one When will it come down? When the top one is smaller than the bottom one Will be big. Now look, I'm telling you One is 3/4 and one is 4/3. So who is the elder one?

[00:20:09]This one is big. So I said to one My brother is small. if it is small then Small current above and big current below. Now look I have a beta. Beta is CE mode In. Current gain in common ammeter mode. Common If there is current gain in ammeter mode my brother.

[00:20:21]So remember me in common ammeter mode and you have it with me.

[00:20:23]What happens? Ammeter in common ammeter mode Will not come. You have the base left and Collector. I said it would have been bigger than one Is. So the base is small, the collector is big so Where will the collector come up? Clean the bottom base Will come. So here it will come IC / IC / I now You are left with common collector mode brother.

[00:20:37]No collector current in collector mode Will come. Ammeter current and base. ammeter current and Base. This is the biggest one I have.

[00:20:44]This is much bigger than one. This is bigger than one and is smaller than one. Ok?

[00:20:47]This is smaller than one. One minute you Will stop. Will hold. too much heat It started. I will make some arrangements.

[00:21:34]Come and see, come and see, let's take a look here.

[00:21:37]Minute here he told us what is sorry IA is asking me now brother, I am beta If I write the formula to you, beta what is the equivalent formula of beta theta The formula will be IC/IB, does I come in it?

[00:21:48]Used to be? No. I have IB. So I How do I remove IE? what to take out Do I take it? I'll take it out. good if I want to remove IE so brother Alpha What is the formula of? Alpha formula It happens I The formula for alpha is IB/e This is the formula of IB/ee alpha. IB I have it. IE I can remove it from here Am. So what do I do? First beta I will find out alpha with the help of. Then Alpha I will substitute here and IB Will get it. I will get it my brother. So I I'll write the formula beta equals alpha / 1 - Alpha. Ok? Sorry, alpha is equal to what?

[00:22:25]Wrong? Alpha equals beta / 1 + beta. So Beta, how much is my brother? will come in 40 upon 41 Cut it off. Ok? 41 since I If I cut this to 40 then point brother 9 times It will be cut. 9 * 1 = 9 here it becomes 400 9 * 4 = 36 brother, this much has been made, only one is left here.

[00:22:44]Three brothers are left here, one is pointing Add zeros 4 * 7 = 28 and 4 * 8 = 32 4 * 7 = 2897 Let's take this as 97, let's say alpha.

[00:22:53]I got you 0.97 Babu, put it here.

[00:22:56]0.97 = IB/E I want IE IB how much brother do I have 28 micro 28 to the power of 10 minus How much do you have? g upon micro Aire and Alpha came to me 97 doing a job My brother, blow both the points from here up Here, tax 2800 upon 97 and 10 You have the power to the minus 6, so here 280 divided by 97 to the power of 10 minus 5 of 9 * 3 = 27, if 7 was 21 then brother Pass 9 is 27 9 * 2 = 18 so 2 points Something will come and 2 points is the only option Dude, finish 2 points, there is only one option and that I can see this one, I can see this one Approximately the answer appears to be It's okay, is it written correctly or not?

[00:23:46]It is written correctly Okay, done, it's too hot.

[00:23:57]But where I'm taking class Okay, today there's a little arrangement here.

[00:24:00]There is something wrong Look brother here the constant of alpha now Look, I won't ask this question.

[00:24:08]Brother. You have to do it yourself. write the formula Constant alpha is 0.95 is 0.95 Ok? I have kept the collector current with me.

[00:24:18]How much is IC? 0.4 ml ampere. Ok? Base Current is asking in common ammeter arrangement.

[00:24:24]So in which one are you getting the base current removed?

[00:24:26]Brother? Base current means IB is asking you.

[00:24:29]How to remove it? can you take this out Are? Now look at beta equals you have alpha is given. If I have the formula for alpha If I write then how much I used to have now Near? There used to be IC/IE. Now we will extract IC/IE How? The problem is that I don't have IE.

[00:24:44]Address. But I know IC. Alpha first Where will I get it from? Base current required Not to me either. I need Babu Base Current. Yes. I have the IC. Yes. See How well it works. IE = IB + IC This You have it. IE = IB + IC IB your It is nearby. IC you will remove from here. His For this, alpha is already given to you. For him You already have Alpha. so 0 95 here I came to IC and upon I came to and here I also keep the value of IC. That is 0.4 and 10 to the power of minus 3, okay? IE Babu, how much will you get in return? here This will make 4 * 10 to the power of minus 4 and this What will be the result of 95 * 10 to the power minus?

[00:25:26]Two. When I solve this, I will have This must be getting made. Oh man, it's so hot Why are such bad calculations coming up?

[00:25:34]IE = 4 * 10 to the power of minus 2 upon 95 so if I write it like this 400 and 10 to the power of minus 4 / 95 so from here you get IE will get it. When you get IE then IB's You will apply the formula IE - of IC IE - of IC Look I Calculation Back The first one will be the answer. The first one is its The answer will be given. The answer to this is the first Going to do. The first one is the answer. Now from us Asking for Faithful Amplification B Transistor Circuit The Value of VCE Common The emitter voltage is How much is the near about for transistor It happens? 1 near is about 1 volt My brother. Ok? Where did the rest of the people go?

[00:26:14]Look, it is not visible clearly. Slight zoom do it. Zoom zoom zoom. Hey brother, how much zoom Will you get it done?

[00:26:20]How much zoom will you get it done, my brother?

[00:26:24]And how much zoom do you guys need? look and Now tell me. So what did I answer you for?

[00:26:29]Did you tell me about you? 7.6 millers. I told it This is the answer. Ok?

[00:26:36]Move ahead. Move ahead. Move ahead. Move ahead.

[00:26:38]Next is fine. Good sir. Now we have again Some new names came from. Again we have some New names have come, my brother. You will see many names What are the names given here?

[00:26:48]Are?

[00:26:49]I am talking to you about DC and AC load lines which Their point of intersection is It is called Q point. cushy point saturation Point. What is his name near you?

[00:26:59]and operating points. All of these are the same Is in the name of. We call this the operating point.

[00:27:03]Are. We call this Q point. This we It is called a rest point. Look how many names there are Its? DC load line and AC load line where But what are their names when they cut each other?

[00:27:12]It happens? Their name is Q point meaning Cushent Point. Rest point saturation point OK operating point Low operating point It is also non-age, so what I told you is Which point became the content point, sorry?

[00:27:23]Saturation point is not the answer only Kashent Point Rest Point Q Point Kashent Point is its name, all the points are of Intersection of DC and AC loads Okay, in line, let's move on now.

[00:27:37]Let's move ahead and see what happens next Hey, go zoom brother See ahead Look, friend, I will open the PDF from here.

[00:27:54]I will do it. which physical quantity is Constant in Joule Thomson Effect. Joule Thomson The enthalpy is always constant in the effect and the formula for enthalpy is H = U + PV H = U + PV enthalpy constant is in the Joule Thomson effect. Joule Thomson The effect was that when certain gases were mixed with Is it passed? From porous flux. So Mostly gases cooling The effects show. But there were two gases which That was hydrogen and helium. He always Shows heating effect. This is in the paper The question arises from the Zuul Thomson effect It explains which such gases are Which always shows heating effect. So that We have hydrogen and helium.

[00:28:29]Which we have believed that whatever is inside the sun The action has landed there, 1H2 + 1H3 together two isotopes of hydrogen combine These are called protium, deuterium, and tritium.

[00:28:38]Let's say. making together helium gas 2H4 and there is a neutrons, which release a lot of energy doing. So energy is released from the neutron.

[00:28:46]and the combination of these two produces helium It is being made. The day this action is received The day it closes, it will all be over, sir.

[00:28:52]Ok? The sun's light fades away that day Will go. Is it okay Baba? then meaning someone else some meaning that is around some other star I will start my revolution Brother. Ok? Have you seen this before Did you know the information or not? quickly Please tell me in the comment box. Some?

[00:29:08]Extra information is also available, Renna Dad. Ok? Let's make the internal energy ideal Depends on the gas. Just come back and tell me I have done it. Internal energy only Depends on the temperature. He gives me this Had to get it done. Ok? over there but The question was isothermal and isomeric.

[00:29:21]Who remains constant in the process? So His answer was Gibbs period energy. Correct Is? Let's go ahead, ahead, ahead, three There are constants. TC TC VC TC TC VC Critical Temperature Critical Volume Critical Temperature Pressure critical temperature critical volume critical pressure okay now you will see Write down their values, see I have TC.

[00:29:43]Pass 8a / 27 hours of everything taught I have made these short notes and put them in the video for you.

[00:29:48]One stop marathon classes are also available for you.

[00:29:50]Passes are available and topic wise classes are also available.

[00:29:52]You have the first book. I did that for You have also been given unit wise classes. PC Then PC has A / 27² And you have VC 3B so I have your Wrote all three in front. It could be tomorrow By changing any of these to your day Let's ask. That is why I say If I have a class of 100 questions I have brought it, so there is nothing outside of it.

[00:30:10]remains. I will do everything you asked me I write. That will give you extra energy I will write it up front. So tell me what else you Needed? Now you have been asked about value critical Of pressure. So brother, this one is done. These My answer is done. critical temperature What happens to carbon dioxide is approximately It is around 31.1 degrees Celsius.

[00:30:24]None of these are options. These All options are there. Ok? I have this answer became. Ok? Where are the rest of the people?

[00:30:31]Is it friend?

[00:30:34]Sir, I am having backlog in B.Sc. second semester.

[00:30:36]Went. So what did I say to read for this?

[00:30:39]The paper should be cleared. Well, the date has just arrived.

[00:30:41]Not there. So the class I am conducting, you Look at these. You will pass comfortably.

[00:30:45]Ok? Don't worry.

[00:30:48]Sir, after studying physics from you, my fear is over.

[00:30:50]Went. Ok. Ok. me very loud Studies are coming. But the rest of the people It is not even here. The remaining number of Why are there less students then live here?

[00:30:57]In session? Number of students living in low Why is it my brother? Ok. Come on, come forward.

[00:31:07]You will see.

[00:31:09]If the critical temperature of a gas is 31 degrees Celsius, which is higher than room temperature Is. So the gas there is liquefied.

[00:31:15]Will go. Can be liquidated option A ends Zero Law always defines temperature The Zero Law defines what it has I have told my internal temperature Energy depends on the ideal gas.

[00:31:26]depending on the temperature by repeating from The internal energy of an ideal gas is Only the temperature answer will be equal to PV/T Constant, these are very easy questions.

[00:31:35]Went to this page my brother PV/T equal Constant is constant here R Let PV/T equal to how much R is Using the ideal gas equation PV = RT, then PV = RD We also have in adiabatic process and the second isothermal process in both Let's use it. So the answer will be both In Isothermal and Adiabatic Processes.

[00:31:52]Ok? Let's move ahead. Let's go ahead my Brother. Hey brother, why should two run away together?

[00:31:59]Only one thing has to be done. Ok. Ok ok. come forward Oh Baba. Come forward. Come forward. our Asking for the dimension of the H parameter The hybrid parameters you have Their dimension is Om. Ok? Good Yes. Then he said in a common bass amplifier.

[00:32:18]phase difference between input signal and Output signal. In a common base amplifier The fuzz difference between input and output It happens to be 0°, it happens my brother. Answer A Will apply. will proceed. Now you have three The amplifier stage is And there are three stages. First of all, three stages I did not have an amplifier. We have There was a two stage amplifier named RC Coupled amplifier. But there are three stages here.

[00:32:38]He made it. And what is the gain of all three stages?

[00:32:40]Is? 50. So brother, what are you asking? We have Overall gain. Hey nothing brother, what was the gain?

[00:32:44]First stage gain multiplied by second Stage gain multiplied by third stage gain Nothing. multiply 50 three times My brother. 50 becomes 50 and 125 and three Put zero, one, two, three, here it is brother, this is the ban The answer has come to you. Ok? It has become 125000 Straight 12,25,000. The Gain of An Amplifier with feedback is known as we have it which is the gain of the amplifier, with feedback What is it called? Forms a close group.

[00:33:10]What is made? Close group with you. Correct Is? go ahead go ahead go ahead go ahead okay Let's go brother, we will zoom again, zoom equal zoom even a little zoom equal zoom dhum dhum emitter Follow is non edge emitter is called follow So the grounded collector circuit is called ammeter follow option number c in practice the Voltage gain this ball spelling knowledge written This game is GAI, the spelling has been done An game in practice is the voltage gain of An amplifier is expression in so which Do you measure it? Decibel. What happens? Decibel.

[00:33:47]dB means decibel. Ok? Next first The answer is speaking. Decibel. Oscillators Our The pass is made in positive feedback. Oscillator The gain of the ideal oscillator is Babu is infinite. Because positive The formula for feedback gain was a = or APF Positive feedback A / 1 - betaA 1 - betaA And if I talk about the oscillator, ideal The beta of the oscillator is equal to one.

[00:34:10]becomes equal due to which its gain becomes infinite.

[00:34:11]It happens and this is what we call it Bark Howson Condition Bark Howson Condition Now You tell me again new MCQs for you I told you whether I gave it or not.

[00:34:21]But if Bark Housen condition is good then you My classes are very long, that's why Because I am explaining all the concepts here.

[00:34:28]I am also telling you more additional things along with it.

[00:34:29]Am. And I promise you if your The exam is after three-four days, so this is my After finishing the class, please Please provide as many video lectures of Physics as possible.

[00:34:37]All those are provided, watch them carefully.

[00:34:40]Have to do it. You haven't read anything, have you?

[00:34:42]I guarantee you will make 75 out of 75 Must be my brother. Ok? and comment box I will definitely give you my feedback again, how are you?

[00:34:49]There was an exam. Ok? Come on, let's go ahead Will increase. will proceed. The Part Of Transistor which is heavily doped. Who The one with the most doping That's what happens. Who is the biggest? They He is a collector. Ok? Very cute.

[00:35:04]My dear brother Answer was very beautiful.

[00:35:06]My dear brother, the answer was. Come forward.

[00:35:11]Will see again. Efficiency of Carnot Heat The engine is given by Carnot's heat engine This is also the formula for efficiency.

[00:35:18]e = 1 – l/power of rho μ – 1 e = 1 – y What happened here? Power μ of L/Rho - 1 This formula also exists. Well here it comes So it was not there. I don't know why I wrote here Gave. Efficiency of Carnot engine This is also a formula. t = 1 - t2 / t1 is okay? Okay, we have it ready.

[00:35:38]By the way, gamma is -1 here. don't cry Would. It has to be applied.

[00:35:43]What is the relation between efficiency of Car Note Engine and Coefficient of Performance K? What does K stand for? This happens For the refrigerator. For refrigerator It happens Babu. And whose efficiency is it? car Note Losses are formed between engines. e = 1 / K + 1 E = 1 / K + 1 Look, my brain is getting numb in the heat. want to do I am moving forward. He is walking behind. e = 1 / K + Will put 1 answer. will proceed. Efficiency of caron engine which is working between Temperature between zero degrees Celsius and 100 Degree Celsius. I've reminded you so many times Am. I have already told you about my short notes.

[00:36:18]Brother. Its difference answer is 26.66% whose answer is near about 27 degrees Celsius Is. 27% write it down. How does he come You will see. Because when we have two Temperature means this one The temperature is ice point. calling it There is boiling point. It also happens that a The engine you have is ice point and Working between boiling point. Ice Ice point between boiling point and boiling point Where the snow freezes near you, then it How much is it, Babu? 0 degrees Celsius and How much is this one? 100 degrees Celsius. Tata's formula is 1 - t2 / t1 t2 / t1 These are always Kelvin scale are taken in. When I add this to 273 If I do it, it will become 373. 273 ads in this I will do it and it will become 273. So there you have it - 1 It will become 273/373 my brother. solve this After doing this, the answer that will come is It will reach 27° Celsius. Because whatever it is The solution will be to multiply by 100.

[00:37:06]Will give. Ok? Let us remember this further.

[00:37:08]Are. This is a direct result. This is a direct result.

[00:37:10]It has been asked many times. Move ahead. Ahead Let go.

[00:37:17]We Hey, why aren't you moving?

[00:37:22]Ok. The barrier voltage at N at a PN Junction for germanium. For germanium The voltage we have is the barrier That's about 0.3 volts. leakage Current means very low current potential flows inside the junction What order is it inside the barrier?

[00:37:39]That is micro ampere. If I am right If yes then D option is its right. Once You can cross check this. But Perfect D is the answer. with forward bias PN junction width of depletion layer.

[00:37:49]Brother current in forward devising when proper If there is a flow then we have its Its depletion layer is its depletion layer This is the case with PN junction diodes which become thinner.

[00:37:56]Gets smaller and smaller This will come in time, the answer will come.

[00:38:00]will go decree okay oh okay or not is it okay my brother or is it not okay my brother Okay, where are the rest of you guys?

[00:38:10]Guruji shared the video back to three Very nice very nice my brother sir All came from Krishna Prakashan's book.

[00:38:15]If you want to solve MCQs of Maths then you can also solve MCQs of Physics like this.

[00:38:17]Get them to do MCQs like Maths.

[00:38:19]I will definitely get it done.

[00:38:23]Ok.

[00:38:29]Now it is clear, isn't it? once my Tell everyone it's clear Is it not coming? When I zoom in Questions before you. So the questions are Is that clearly visible or not my brother?

[00:38:37]Are my questions clearly visible or not?

[00:38:39]Brother? This should be clearly visible, friend.

[00:38:41]Now when I am getting it solved by zooming.

[00:38:44]Please write once in the comment box, friend.

[00:38:45]Do you still have the question invisible?

[00:38:48]My brother?

[00:38:50]What are you saying to us? The Correct Relation Between Vrms and molecular weight. So look there were three. VRMS Was I had 3RT/M V 8RT / πM in And VMP was 2RT/M This was it. If I'm not mistaken this is my There were relations nearby. I wrote to you first Were. So the answer to this will be 3 and it will be passed.

[00:39:19]How much will be its answer, my brother? 3 One. The highest value among these would be That is Vrms. The greatest speed It is smaller than the average you have Speed. The smallest is the one you have the most Probable speed. Most Probable Speed.

[00:39:33]To find out the most likely speed There is one more way. 2 2 3 5 2 meter like this within a system of seconds The speed of the molecules is given. Most Probable Speed ​​is asking you. So the most The one that is repeating the most number of times is two.

[00:39:45]So two is the answer. Ok? number of Degree of freedom of each molecule of mono Atomic gas. So brother, three will come. only its You will get a degree in translational motion.

[00:39:54]Rotational will be zero for this. So the answer to this It will be three. Ok? Mono near you Three dies were for atomic.

[00:40:00]Polyatomic five and triatomic I had taken six. I have already told you. Correct Is? There is also an atomicity formula on this Comes. What is gamma = 1 + a / f?

[00:40:08]Degrees of freedom. Ok? You can further them Can solve it. Ok? 1 minute again I am coming. We Let's look ahead brother.

[00:40:52]Told us RMS speed at room temperature of molecule of certain die atomic gas is Found to be 1920 metres per second. So brother Whose does it belong to? hydrogen gas is Is. You can remember it straight away Hydrogen gas will come. Hey Wonderwall Gas We give one more name. Did I tell you It was named as real gas equation.

[00:41:09]Was? No my brother. I had said this Also called real gas equation. also what Are you saying this Babua? Real gas equation also My brother says. So we call this real gas.

[00:41:18]They also speak equations. So p + a/ v² v - v = rt This is the ideal gas equation sorry.

[00:41:25]Hey brother, the weapon fell, no problem.

[00:41:28]Is. What do we call this? Real Gas Equation. This is in the ideal gas equation This is the equation made by making corrections. Real Gas equation. Ok? where a / v² asked Also goes. adhesion between two molecules There is pressure. b of a gas molecule There is volume. Ok? Let go Ahead.

[00:41:49]Look ahead, it's getting very hot.

[00:41:51]really too much For thermodynamic systems, work done in Process Depends on Thermodynamic System Brother, it depends on whom the work is done.

[00:42:00]on the path because this thermodynamical function Not only this, it does not depend on temperature.

[00:42:03]depends on the way if my Inside volume v1 near constant pressure If it fills from to v2 then how much work is done v2 - v1 will be a straight isomeric process The work done is isochoric and is zero Okay, all four of them are done, I told you.

[00:42:15]I have got it written. What did you not get written? Oho What did you not get written? You will say absolutely Will get it written. Come to understand further. The Absolute Scale of temperature is same as perfect gas Who is equal to the scale? Absolute Scale of temperature. Of these, the class scale The electron equation is dp / dt l / tv2 - v1 dp / dt = l / tv2 - v1 good Which option is visible? l / t l / t l / tv2 - v1 hey good good good over here dp / dt dt up watch carefully. be careful Look Look carefully. Look at this one It is the same but this is wrong so this is also wrong.

[00:42:44]This is also wrong, this is your right dp / dt = l / t v2 - v dp / dt l / t v2 - v Absolutely correct perfect answer further ahead Moving forward my brother go ahead go ahead okay quickly Let's try to beat the heat, friend.

[00:43:02]You guys are having too much fun I must be sitting under the fan, under the AC.

[00:43:06]The fan is getting worse class still I am taking your class because you You have too many exams, too many Question. Ok? Let me know if I Should I show you the speed brother, it's going so slow It is here. You'll see this later, if I I am showing it like this, so I am sweating here.

[00:43:21]Everything is happening. Ok? Something No. Sir here specific heat of a Saturated vapor pressure. We have Specific heat is what is called specific heat.

[00:43:29]They say heat. of saturated vapor pressure There is specific heat. Satisfied whom?

[00:43:34]Do you speak? to the saturated pressure. So that It is negative, Babu. What are we getting from this result?

[00:43:37]Should I prove it to you? Which of the following Is not a thermodynamical function? So work It cannot be done, my brother. I have just come to tell you Was. What does this depend on? only talk It depends on you, my brother. tell me in advance I had already done this too. Ok? These which one by one Why repeat things like this again and again?

[00:43:50]Are you an investor? Ask something for the New Year I have been with these people. Now watch this fun There is a question. Now look at this funny thing There is a question. Its answer is fake.

[00:43:58]This is a very sweet question. Very beautiful I have a small question. very sweet question Is. What are you saying? An Ideal Mono Atomic gas is taken round a sir. Sleep One Figure the work done. full round of the cycle Inside we have Work Done.

[00:44:11]But if I ask like this, like this, like this, like this like this, like this, anyway the work done is zero, like this also Work done is zero and volume is zero Because whatever pressure is there here and whatever the volume is here What is the volume in this cycle?

[00:44:26]If I talk about volume, what is it?

[00:44:28]It will be constant on this one too.

[00:44:30]What will be the volume constant and What will be the difference in volume between zero and Here also how much will d be zero which is like this By doing this you have created it in this process How much is Work Done coming in? Zero. because dw The formula is P * DV and when If DV becomes zero then why the product brother I? Now how did it become zero like this? as much as here Look carefully as you go. as much as here He might have just returned. Whatever work is done here, It will be here only. Work done net work done which will come That Zoro because the one here will be positive.

[00:44:56]How much will the negative here come after deduction?

[00:44:58]Total finally zero. That's how Zero came about. Ok?

[00:45:02]Sometimes work equals force * displacement Apply it. Put displacement zero.

[00:45:06]The concept I just told you doing. What are you saying to us now? Ar Dad See.

[00:45:15]O dear Look at the answers you have. If You don't have this clear visibility right now.

[00:45:24]Big.

[00:45:33]Oho Ok. Now, brother, this is a bit dirty.

[00:45:39]Writing on this page. Watch One Minute Volume We have the expansion coefficient which we call alpha Represent from. Represent from whom Do you my brother? From Alpha. then equal Who gets it? vo l / ov dv/ dt and et Constant pressure was not visible here.

[00:45:53]Used to be. So you please note this. These This is your answer. Expression for Joule Thomson Effect. Keep the Joule Thomson Effect to yourself The mu that we had for this The Joule Kelvin coefficient is formed, which How much is zero for ideal gas?

[00:46:05]For whom is zero ideal?

[00:46:06]For gas, which is zero, ideally for gas.

[00:46:08]If μ is zero then the value of μ is 1 / cp 1 / cp remove this from here tdv/dt dv/dt and minus dv/dt - you which I I am writing it, please note it down if you Clear options are not visible here.

[00:46:22]If you don't see clear options My brother, what I am writing here Please note that down along with it.

[00:46:27]I am writing in front of you.

[00:46:38]Hey brother, if you don't study then class is going on.

[00:46:40]No? Ok. Read it from there. Sir, none of your Is there an application or not? No, my There is no application. Ok. Application Haven't read it.

[00:46:50]Ok. The application has not been created Dear Folks. Right now we have someone okay. Now Let's move ahead.

[00:46:57]What are you saying to us now? lowest temperature can be achieved by the lowest means Low temperature can be achieved by Can it? Speak with a kiss particle. This I will speak in English. This little It's a strange name. adiabatic Diamagnetization. adiabatic Demagnetization. He meets her and then his Pass bola relation between gives energy and The relation between enthalpy and g equals g equals h + tdg/dt At constant pressure. D Write this down = h+ tg/t Okay, at constant plus, let's move ahead brother.

[00:47:33]I will zoom in on those that are not visible.

[00:47:35]I am writing to those who are not visible.

[00:47:37]I am writing by zooming in. Okay, let's move on.

[00:47:40]Come Let's go brother Good absorbers are always good emitters Are. Like throwing a jacket into a bucket Dip it. You wore it in winter. shirt To drown in water more than what to consume will be? Inside the jacket. And when you Who will you squeeze out the most?

[00:47:59]Will it come out? Jacket service brother. So those who are good Absorbers are as good as emitters There are. who told? The Kirchhoff brothers Said. And this rule was Black bodies.

[00:48:08]for the spectrum. of black body radiation He did it for this. Ok? When Black Radiation of the body was explained. So Kirchhoff's Law was that good absorbers are good Ammeter. This statement is called Kirchhoff's Law.

[00:48:18]According to one's law, we say that λ mt is always equal to the constant And here comes the constant, a bean constant.

[00:48:24]Its name is b then λ m * t is equal to Two constants are visible in the same option We will move forward Look, this is a bit of a big question for you.

[00:48:35]We have to understand this carefully, two or three numerical Not yet, see two more I did not get the numericals, everything is fine.

[00:48:39]All the simple numericals are just filled Send it brother, this is calculation, what work do you want to do?

[00:48:44]You should put these questions at the very end.

[00:48:46]Whatever you have, whatever these are given to you The questions are given to you. These most Do it at the end. There is a metal ball that The surface area is a. 200 cm² gives you Found it. How much temperature is given by him?

[00:48:55]Is? T equals that I have got 527 In degrees Celsius. I can get the area Gaya 200 cm. So 200 * 10 to the power 4 meters squared of minus. If I make this Let me convert it into meters. temperature We refer to the temperature of the surroundings as t note.

[00:49:06]Let's represent. Because it is 27 degrees It became Celsius. When you add 273 to these If we add plus 273 to it, it will become will go to 800 Kelvin.

[00:49:14]When we add 273 to this, it becomes 300.

[00:49:16]Calvin.

[00:49:19]Then he was talking to himself about the emissivity of The metal is so 0.4 di. Rate of Loss of Heat is asking us what would a sigma be?

[00:49:27]Do you have it? Stephen Constant, who was so is given. So I continued with the session It has happened. Its answer will be 182 watts. and this You have the answer given to you. We have This happens. Ok? Immiscibility occurs e Sigma happens we have Stephen Constant. A is area. T happens We have temperature and T note Temperature of the surroundings. Now all this data If you put it, you will understand. I I will not calculate this at all. already You have to. Ok? Now Next Let's move towards the question. Now look ahead.

[00:49:56]Now look ahead.

[00:49:59]Will see again. Will see again.

[00:50:06]If we have E total energy which is is emitted by a body, is emitted and T is the temperature of E If there is maximum energy then who among these can be said?

[00:50:16]Is this relation correct? E is directly Proportional T to the power of four and E maximum Proportional to T to the power of five. E is proportional to the power of four of T and E is the maximum proportional power of T 4 of. This is called Boltmann's Law.

[00:50:27]Stefan Boltmann Law. Ok? Or Stephens Loss. What do you call this? Stephens Law.

[00:50:32]That's what you have with Steffes' Law.

[00:50:35]Steffes' Law. Ok? This Black Body Have a concept of the radiation spectrum Is. Meaning where you have a chapter called Radiation Let's read all the properties from there.

[00:50:44]It is given in front of you. spectrum of Black body radiation. Black body radiation How is the spectrum of always is continuous and the radiation that occurs He always keeps his watering can on the path.

[00:50:53]How much pressure does it apply? P = U/3 where We call U the energy density. This too You are asked. Then it comes to us One has the Planck radiation formula which whose average energy do we have?

[00:51:05]Does it come? For any harmonic oscillator h new up to e power h new/ kt and minus of 1 and the Planck radiation formula from this When the drive takes place, it is asked whether it is lager or not.

[00:51:16]What does wavelength convert into? So My brother converts to Relegance Law and in the minimum or shorter wavelength which It converts, it converts to green In law. This has already been asked of you. Asked Will go. Ok? Let's move ahead.

[00:51:32]So see the next question, now the interesting thing Law is applied when If the wavelength is less, if it is shorter wavelength then your Near medium wavelength many wrong thing larger Wrong thing Smaller wavelength an option is the Correct Proceed if a container contains is water at 100 degrees Celsius and that Cools from 100 degrees Celsius to 80 degrees Celsius in T1 minute and then a We have 60 degrees to 80 degrees Celsius Celsius becomes t2 in how many minutes brother, he is saying that he has minutes in these Which relation is correct? So brother, this one relation you will remember this later The temperature time will take longer first.

[00:52:07]Compared to the one. right next to you at 100° It will take less time to reach 80°C.

[00:52:12]But if it is reduced from 80 to 60 then it is too much.

[00:52:14]It happens, right? Newton's Law of Cooling.

[00:52:16]We will move ahead.

[00:52:18]Now we have some circuits we studied.

[00:52:21]RC circuit, LR circuit, LCR circuit.

[00:52:24]We study three types of circuits and all three Inside we are asked for time constant Is. time constant if I start talking For a time constant CR circuit, What is the value of RC and LR circuits?

[00:52:33]It happens? For an LR circuit, it is L / R So it is also asked that for LR circuit The time constant for the L/RC circuit is If you take RC then your answer will come. RC asked you.

[00:52:43]Its charging equation can be given as comes close to Q = Q not 1 - E of power T/ RC and while discharging The equation comes out to be Q = Q not E Power - T/RC Whose is this? This is it discharging and this is charging Number. Ok? Now the time is here Constant I have that in which There is a relation for the charging person, q = 2/3 q Not whose is this? Charging relation of If I put rc equal to t then its The charge is how many times the maximum charge goes? 2/3 times. be in discharging goes up to 1/3 times. Write all this down. all all It is useful for you. In which? Discharging In. Now you will say, brother, you have told me so much.

[00:53:24]If you have given it to us, tell me whose else.

[00:53:25]of the LR circuit. So in the LR circuit, is the growth of the current. LR circuit LR I have a current growth in the circuit And the current decreases. The current increases And the current decreases. Current growth is near you There is an equation. The time period for this How much did you tell? L/r Who is this time?

[00:53:42]Period? Ok? It has a formula = I Note 1 - e to the power - RT / L RT / L Ok? This is the formula. And here The maximum current is the current It becomes 2/3 of the maximum current. What But? At this time constant. Current Dake Ka I have the formula.

[00:54:01]I = I not E power minus of RT/L These flowers are for you to remember. these flowers They are very useful to you. You can screenshot Take it. Take a note down. Whatever you feel like Do it. Ok? Whatever you feel like. Sir Yes, I have scored 506 out of 800 in B.Sc.

[00:54:21]In the first semester. Ajay Goswami Very Good. very nice.

[00:54:25]Ok sir. Sir please help me in Physics 2nd also Do it. Very good my brother.

[00:54:30]Congratulations. You teach very well Sir. Absolutely my brother. If you people's If you get good marks then definitely give feedback Please give it to me friend. We know what we taught So, whatever content we are teaching you, Whatever is being given may be beneficial Is it happening or not. Ok? Don't worry.

[00:54:42]Of course, we will stay together till your exams.

[00:54:44]Be absolutely rest assured.

[00:54:47]Ok. Is it okay Ajay? Okay my brother.

[00:54:54]Let us now look further. You hope My brother must have taken the screenshot.

[00:55:00]You must have finished, okay, oh, it's okay, Babua, okay.

[00:55:04]yes ok I once again cool my little I will come after drinking water brother, if you want Take a screenshot of this question.

[00:55:57]Okay, you must have taken a screenshot.

[00:55:59]I must have taken down the note while moving forward.

[00:56:02]Shift classes are being run, brother, see.

[00:56:03]Look, it's so hot, yet I'm yours I am taking class, okay, hey Baba, okay Let's say what the frequency of an AC said In India. What is the frequency of AC brother?

[00:56:16]You must have noticed that it is 220 Hz. The Current of output of an ideal current source.

[00:56:21]So how much current would he always have with him?

[00:56:23]Is? The output of an ideal source would be zero.

[00:56:25]Is. Brother, let's move ahead.

[00:56:28]Only a few questions are left. You Please maintain patience. Your class is coming soon I will finish it. Just a few more questions There are survivors. There are not many questions.

[00:56:36]Please, please, please stay in class.

[00:56:38]My brother. Why is it not working?

[00:56:51]In a network, Kirchhoff's laws are applicable such that the current are unknown the equations are to How do you make those equations, brother?

[00:56:58]It is in the loop that you form Kirchhoff's law, which You must have applied it, a loop is formed inside it.

[00:57:01]So you apply oh Kirchhoff's law in your loop You plant it, you must have made a forest nearby I will teach two things in KVL and KCL, you must have made loops like this, right?

[00:57:10]Here you have applied resistance.

[00:57:11]If there was voltage here then brother UP Question: What is an n-type semiconductor like?

[00:57:15]So the n type is negatively charged my bro it's okay it's electrically neutral And brother, if it were a semiconductor then it would be neutral It has the majority of charge carriers.

[00:57:25]Electrons are the majority charge Careers are fine, however its negative I will charge the answer, okay, you will check it.

[00:57:32]OK Done Next What are you asking us that absolute temperature in intrinsic Semiconductors are absolute temperatures These intrinsic semiconductors have so voltage so voltage so voltage Absolute temperature for germanium Absolute for Sorry Germanium temperature near me in germanium Shouldn't have said absolute temperature He should have said voltage for this For germanium, it comes to 0.3 voltage.

[00:58:03]Yes brother, it comes out to be 0.3 volt.

[00:58:05]Germanium has its own voltage.

[00:58:07]Ok? Moving forward. See further. further forward The output voltage in bridge rectifier.

[00:58:15]Output Voltage in Bridge Rectifier how much is a?

[00:58:23]We Why is it not working?

[00:58:30]What is he saying to himself? Look at the attention From. The output voltage in the bridge Rectifier. Output Voltage Bridge How does the rectifier work? Half Wave Signal Full Wave Signal Sine wave signal output voltage bridge Rect to bridge rectifier ka to bhai full Wave will come because full wave rectifier We have bridge rectifiers as a special case Whose full wave rectifier is this? Then our speaking nearby That rating of etch diode. Who are you talking about?

[00:58:55]Used to be? For whom has he written PIV?

[00:58:58]Good PIV means fourth rating near you This is saying that diode in a bridge Rectifier is equivalent of center tape Rectifiers read here Bridge PIV of each diode of the rectifier If the rating is of center tape distance then one This unit is just halved, this is the result What's new in this, my brother?

[00:59:18]This is the result my brother, okay, go ahead.

[00:59:21]Then you will see the rating of diode accid Pass rating of diode exceeds the diode Conduct Poorly the diode is destroyed. The Diode.

[00:59:31]You should cross check this once. Brother I am a little confused in this. to me this You should take a screenshot of the perfect answer.

[00:59:38]This is a new topic we got. This you Please cross check it. Ok? This I Gave you a question as homework. You cross Please check it. Those who know, please comment on the answer.

[00:59:45]Please give it in the box. I will do this later I will justify it. there is a need of Transformer. Why do you need a transformer?

[00:59:50]it occurs? center tape full wave rectifier For half wave rectifier ok center tap this is not the top tap Write it like this for full wave rectifier We will have the answer to this, now we will Let's go ahead and see here.

[01:00:02]Finally, we have come to finish the question.

[01:00:04]towards We are almost done with our questions.

[01:00:08]Finish last we have transistors What is also called transistor semiconductor triode semiconductor triode This happens because whenever you If it is PNP or NP then PAP We have 1 2 3 so what are we three types of Do you use it? Semiconductor use inside it We do. That is why it is called a semiconductor Triode says my brother. What name Does this happen? Semiconductor Triode.

[01:00:34]Hey look, functional Hindi. Let me see Am. I will try.

[01:00:40]Sir, you work very hard for us. Heart Thanks from. But you B.Sc. second semester Tell me something in Physics which is mentioned in the paper Found kept. You will find it kept in the paper. People First watch this class. Before this Watch the number of classes provided Please do it. Look brother, let me tell you the reality.

[01:00:54]I will delay your classes a little bit.

[01:00:56]I am doing this because on 17th May I have a There is an exam. There is a lot of exams on 17th May.

[01:01:00]Ok? But I still like your classes.

[01:01:02]I am not stopping. Provide you with classes I am doing it. Take time for those who have exams Is. You would be seeing if you guys He said, brother, we have an exam, so I will tell you I provide classes. Ok? You Don't worry. Whatever your exam is, First, I will conduct the class. And you are the Guru Jambeshwar University (GU) and MJP If you are, be absolutely sure because Other university exams are going on.

[01:01:17]I am providing classes to them. And When your exams will be held then you will also Classes will be provided. marathon Classes will also be provided. So Be absolutely rest assured. Content for all Full provision will be provided. Ok? and right now What work will you do? These classes which Hey brother, solve PYQ and know the syllabus of all So is the bean. This is the question in your exam.

[01:01:32]Are coming. This is what happens in MSU exams.

[01:01:34]Are coming. This is CCS University I am going to appear in the exam. This is DDU's I am going to appear in the exam. Ok? So you Why do you do this that you are our brother?

[01:01:40]Bring a special class. of all universities The syllabus is same. Do you have this question?

[01:01:44]Not there? Is your guru Jambeshwari Don't you have university questions? What Don't have MGPR questions? Brothers all Almost all questions in the university The beans come. Ok? Let's answer the first one What happened my brother? what about transistors What is it called with us? Semiconductor. relation Among emitter current, base current and collector Current. Which is the biggest current? Ammeter Current. Sorry. Not the collector, but the collector is the most It is a big terminal, my brother. So which one Is there current? The largest ammeter current. So Whatever comes equal to IEE will be IB + IC. IE Whatever comes out equal will be IB + IC. This would have been and here it is asked that IC is equal to so IC is equal to If I take it out then IE - IB should come. IE-IB Should come. Correctly given. But IB If I take out IB, what will it be equal to?

[01:02:22]I The IC of minus is wrong. This is also wrong. These Also wrong. All the options went wrong. First The option is right, my brother. This Main Relation Was. This was the most important relation you had.

[01:02:32]Which is the bigger current? any Remember one thing about transistors. You When making transistors PNP You made the transistor, did you make any transistor made PMP transistor or NPN transistor my brother question If you are asked to do one thing, do the next.

[01:02:42]I will write the question here first on the page.

[01:02:43]I'll finish with a few additional questions, whatever.

[01:02:46]I will tell you what they are and leave, don't worry.

[01:02:51]Are you not erasing it? Hey, how are you doing it?

[01:02:54]Why are you not erasing it, I have gone crazy What, why are you not erasing it, look I am gone brother I am gone see these a Transistor Circuit The Emitter Current Is 10 Millie Emmpier. Okay brother. ammeter current Meaning the highest current will be 10 milliamps. From this All the answers will be short. The collector current is 0 9 ml ampere. And it got better. So base He is asking about the current. What will be the base current?

[01:03:18]IC of IE minus IEE - IC 0.9 out of 10 Reduce it brother. So it will come to 0.1 milliampere Your answer. 0.1 milli ampere will come brother Your answer. This option is correct. Now its If I ask any questions that I have after Babu, should I make a transistor like this?

[01:03:37]Transistor whether it is NPN or PPN This is how a transistor is made.

[01:03:42]We have an ammeter, this is our Pass base and this is what we have as collector Now whether you have a PNP transistor Whether you have MPA transistors I made PAP, Babu, so what about the battery?

[01:03:52]I'll put the positive terminal here and I will connect the negative terminal to the pin.

[01:03:57]So you should always look at this carefully, if here n If I talk about the type, it is coming out negative.

[01:04:01]It is positive and negative. But this P type high Who is he connecting with? Connecting to the negative For the face here. So this always happens Forward biased.

[01:04:11]This is always reverse biased. What Does it happen Babu? always reverse forward bias and backward bias. Any transistor For this, the emitter base junction, whether it is Be it NPN or PNP, these are always Forward bye. Your questions will appear in the paper.

[01:04:23]My brother. What do these always contain?

[01:04:25]Forward bye. And if I start talking Base collectors are base collectors These are always the reverse my brother Biasing base collector always occurs in are in reverse biasing So you have this concept by doing something like this when If I start talking about forward biasing, The ammeter base is always constant whether it is NPN or PNP ho forward by and if to talk If I want to reverse bias then our Pass Base Collector largest terminal largest largest The terminal which is the largest The terminal is the one the ammeter is smaller than Hey my brother sorry he is the eldest collector terminal would be smaller than that The ammeter is smaller than its base The current is the largest, the ammeter is smaller than that There is a collector and smaller than that is like this By doing this you have the current There are relations of. Ok?

[01:05:18]The papers will be held in MJPRU, my brother.

[01:05:20]Start in a day, don't worry. Ok.

[01:05:24]Hey friend, I don't have everyone's admit card.

[01:05:26]I am writing. Those of MGPRU who have There is a possibility that the exams will be held on May 20.

[01:05:32]Your exams can start any time later.

[01:05:33]Are. and Guru Jambeshwar University The most likely date for the exam is June.

[01:05:37]I am thinking that your exams will be held in June.

[01:05:38]I will go to Ok?

[01:05:42]Hey, it is for all universities, friend. I I am saying it again brother, whether you Whether it is from MJPRU or Guru Chambeshwar are from the university and one last thing I will tell you people Let me tell you one thing, whatever you say Are you there, see the result, result, result?

[01:06:01]I am writing something here As many as the people of Guru Jambheshwar University You people are responsible for your results, now you should not do this.

[01:06:12]I am asking brother because you eat mangoes and seeds.

[01:06:15]Don't have to count. The day your result It will be announced inside that university.

[01:06:19]Only 10% children pass. This time only 10% children pass, worst result This time it came from Guru Jambheshwar University.

[01:06:27]Is. Too many kids are failing here.

[01:06:29]Are. Those people who are coming after checking the copy They are saying that there are too many children here.

[01:06:33]What does it mean if you are failing?

[01:06:34]that first all the children should be examined The forms will be filled. when your Examination form will be filled and completed So 13th May is your last date to fill the exam form.

[01:06:42]To fill. Around that, May 11, May 10 One day, tomorrow or the day after tomorrow, Monday, Tuesday, any day tomorrow, the result Will not come. Yours on Monday or Tuesday The result will be 100%. because first These people will get the examination form filled.

[01:06:58]Then your result will be announced. Some?

[01:07:00]What happens to the children? Mindset happens Not if he fails in all his subjects.

[01:07:03]If she goes, he leaves the university. Whereas Why do you have backlogs in all your subjects?

[01:07:07]If it does not come, you can give their back form.

[01:07:10]And you don't get your semester back. You Will give exam before second semester. When You will reach the third semester.

[01:07:15]Together you will get both the first and third I have to give the exam brother. Ok Hum Sir To MJR University Ke Exam Are coming. Then what should we do? Hey brother Exams are coming. Watch the playlist.

[01:07:26]Look at the previous year's paper. Your MJPI I also took the previous year paper there.

[01:07:30]It is kept. Complete Thermodimes Questions All of them have been done. You see this Those questions will all be the same brother.

[01:07:35]Ok? So whatever university you are from So classes are available for you. you go Watch the preparation in a fun way. Ok?

[01:07:42]Yes, some exams can be postponed till June. But Your exams start around 20th May.

[01:07:46]It will be done.

[01:07:52]DCSC I have mentioned in short notes I have completed it so I have put things here I have not told anything because the short notes I got as much as we needed.

[01:07:58]It has happened. Ok? in the third semester when If you have classes then you will have the proper Because that is yours in the described form If there is an exam then complete theory.

[01:08:06]Numerical sub will be provided to you.

[01:08:08]Ok? So, I will end today's class here.

[01:08:09]I finish paying. See you next In the video. Whatever you like about the content Please please as soon as the class is over Brother, please do write your feedback later. how were you Class. So see you in the next video. Then Tak bye take care. Love you to all.
