Question

A 4 micro Farad capacitor is charged by a 200 volt supply. the supply is then disconnected and the charged capacitor is connected to another uncharged 2 microfarad capacitor. how much electrostatic energy of the first capacitor is lost in the process of attending this study situation.​

Answer 1

Answer:

The loss of Electrical Energy is 400N.

Explanation:

Here,

Electrostatic Energy of first capacitor= (200×4)= 800N

Again, Electrostatic Energy in the second capacitor= (200×2)= 400N

So, the loss of Electrical Energy= 800-400= 400N
