The average power dissipated in a pure inductor

A

`VI^(2)`

B

zero

C

`1/2 VI`

D

`(VI^(2))/4`

Text Solution

Verified by Experts

The correct Answer is:
B

The average power disipated is
` P_(av) = VI cos phi ` where `cos phi ` is the power factor .
For pure inductor , `phi = pi/2 `
` :. Cos phi or P_(av) 0 `
Thus the average power dissipated in a pure inductor is zero .
