A capacitor of capacitance `20muF` is cahrged to 10 V. what will be the increase in its potential energy if the potential difference is incrased from 10 V to 20 V?

A

`3xx10^(-4)J`

B

`3xx10^(-3)J`

C

`15xx10^(-3)J`

D

`25xx10^(-4)J`

Text Solution

Verified by Experts

The correct Answer is:
B
Increase in potential energy`=(1)/(2)C[V_(2)^(2)-V_(1)^(2)]`
`=(1)/(2)xx20xx10^(-6)xx300=3xx10^(-3)J`
