[00:00:00]DC lines are much easier to connect to each other, unlike AC. Let's connect two AC lines together. Here I have my car inverter running on the 12-V battery, and here I have the city power line.

[00:00:11]Both of them are exactly AT 120-V AC.

[00:00:15]AND THAT'S WHY YOU don't try that at home. Being 120-V AC is not enough. See, the sine wave is coming from the city, and the square wave is coming from the inverter. They are not the same shape, and they are not in phase because their frequencies are slightly different. That creates huge voltage differences. To connect them, they must be the same shape, same frequency, same phase, same voltage level, same background, same ethnicity, and graduated from the same school. But, for DC, we just need to make sure the voltage levels are the same. Right now, I have rectified the two sources with a diode and capacitor, and we can easily connect them together.

[00:00:52]Yes, we need to make sure they are the same voltage level and the same polarity, of course.
