Practice mode Alternating Current

In a purely inductive AC circuit, how does the current compare in phase with the applied voltage?

Correct answer D. Current lags voltage by 90°

Explanation

The back emf of the inductor opposes changes in current, so the current reaches its peak a quarter cycle after the voltage. Current lags voltage by π/2 rad.
