The energy required to charge a parallel plate condenser of plate separation d and plate area of cross-section A such that the uniform electric field between the plates E, is

A

`1//2epsi_0E^2//Ad`

B

`epsi_0E^2//Ad`

C

`epsi_0E^2Ad`

D

`1//2epsiE^2Ad`

Text Solution

Verified by Experts

The correct Answer is:
D
`1/2epsi_0E^2Ad`
Explanation: The energy per unit volume
`=1/2epsi_0E^2`
Volume of space between plates = Ad
Total energy stored = `=1/2epsi_0E^2Ad`
