A coil of inductance `L` has an inductive reactance of `X_(L)` in an `AC` circuit in which the effective current is `I`. The coil is made from a super-conducting material and has no resistance. The rate at which power is dissipated in the coil is

A

0

B

`IX_(L)`

C

`I^(2) X_(L)`

D

`IX_(L)^(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
For pure inductive circuit `phi = pi // 2 `
`P_("avg") = V_(rms) I_(rms) cos phi = 0 `
