Consider the arrangement of three plates `X,Y` and `Z` each of the area `A` and separatioin `d`. The energy sotred when the plates are fully charged is

A

`epsilon_0AV^2/2d`

B

`epsilon_0AV^2/d`

C

`2epsilon_0AV^2/d`

D

`3epsilonAV^2/d`

Text Solution

Verified by Experts

The correct Answer is:
B
Two capacitors are in parallel.
`:. U=1/2C_(n et)V^2`
`=1/2(2C)^2=CV^2`
`=((epsilon_0A)/d)V^2`
