Question

Battery does 200 joule of work in charging a capacitor the energy stored in the capacitor is

Answer 1

hii mate!!

in capacitor work done is stored as potential energy that is U = 1/2 qv ,,W = vq ,,so U =1/2 x200 =100 
 
hope it helps !!☺☺☺

Answer 2

Answer:

Energy, E = 100 Joules

Explanation:

It is given that,

Work done by a battery in charging a capacitor, W = 200 Joules

We have to find the energy stored in the capacitor.

Work done by the battery is, W = QV............(1)

Where q is the charge and V is the potential difference.

Energy stored in a capacitor is, E = 1/2 VQ  

Energy, E = 1/2 × W (from equation (1))

So, E = 100 J

Hence, energy stored in the capacitor is 100 Joules
