If there are n capacitors in parallel connected to V volt source, then the energy stored is equal to

A

`(1)/(2)n CV^(2)`

B

`(1)/(2)(CV^(2))/(n)`

C

`(1)/(2)CV^(2)`

D

none of these

Text Solution

Verified by Experts

The correct Answer is:
B
Energy stored by an system of capacitors `i`
`= (1)/(2)C_("net") V^(2)`
where `V` is source voltage
Thus, `n` capacitors are connected in parallel,
Therefore `C_("net") = nC`
`:. E_("net") = (1)/(2)nCV^(2)`
