What will be the phase difference between virtual voltage and virtual current, when the current in the circuit is wattless

A

`180^(@)`

B

`45^(@)`

C

`60^(@)`

D

`90^(@)`

Text Solution

Verified by Experts

The correct Answer is:
D
Power `(P) = E_(rms) I_(rms) cos phi = 0`
Since it is wattless current. But `E_(rms) !- 0, :. Cos phi = 0 or phi = 90^(@)`.
