[00:00:00]Right now this current is passing through this coil at normal temperature.

[00:00:04]If I pour this liquid nitrogen on this coil, its resistance should decrease. Meaning, this top is a little bit, because there is still no special resistance, so it will not burn that fast, but still, please turn off this light.

[00:00:26]Its glow means that it is able to pass a little current easily. And what happened earlier was that the electrons inside the metal were in thermal agitation. Now the thermal agitation, the zigzag motion, has reduced.
