Question

An ideal inductor consumes no electric power in A.C. circuit. Explain.

Answer 1

Explanation:

Loss of power in an inductor is zero because current lags behind the voltage by 90°.

In one half cycle voltage is positive and in other half cycle of sinusoidal wave current is negative, they will cancel out so the power loss will be zero.
