Derivation for Expression of Potential Energy For Capacitors
In this video podcast we are going to study derivation for expression of potential energy for a capacitor.
This topic of today is very important from the view of Boards. Specifically the part where we go for defining and deriving for expression of energy density of a parallel plate capacitor...kindly take a note for the very same..
In the last part of the video u find that several questions have been asked to u...please pause the video at that very point...n try to answer them in ur copies...
