When an A.C voltage of 220 V is applied ...

When an `A.C` voltage of `220 V` is applied to the capacitor `C`

A

The maximum voltage between plates is `220 V`

B

the current is in phase with the applied voltage

C

the change on the plates is in phase with the applied voltage.

D

power delivered to the capacitor is zero.

Text Solution

Verified by Experts

The correct Answer is:
3,4
`E =CE = E_(0) sin omega t`
`Q = CE_(0) sin omega t`, therefore `E` and `Q` are in same phase.
In case of capacitor, `phi = (pi)/(2)`
`:. P = E_("rms") I_("rms") cos phi = 0`
