A capacitor is used to store 24 watt hour of enegy at 1200 volt. What should be the capacitance of the capacitor?

A

120 mF

B

`120 muF`

C

`24 muF`

D

`24 mF`

Text Solution

Verified by Experts

The correct Answer is:
A

`U=24 xx60 xx60J , V = 1200`
`U=1/2 CV^2implies 24 xx60 xx60 =1/2 xxCxx144 xx10^4`
`impliesC =120 mF`
