A `100muF` capacitor is to have an energy content of `50J` in order to operate a flash lamp. The voltage required to charge the capacitor is

A

`500V`

B

`1000V`

C

`1500V`

D

`2000V`

Text Solution

Verified by Experts

The correct Answer is:
B
From the formula `E=1/2 CV^(2)`
`:.50=1/2xx100xx10^(-6)xxV^(2)`
Or `V^(2)=10^(6)V`
or `V=1000V`
