An alternating current of frequency f is flowing in a circuit containing only a inductor L. If `V_0` and `I_0` represent peak values of voltage and current respectively , the average power given by source to inductor is equal to ……

A

0

B

`0.5 V_0I_0`

C

`I_0^2 2pifL`

D

`V_0I_02pifL`

Text Solution

Verified by Experts

The correct Answer is:
A
For the circuit containing only inductor
`therefore delta=pi/2`
`therefore` Power `P=(V_0I_0)/2 cos delta=0`
