In an ac circuit,the current in an inductor A) leads the voltage by 90^$\circ$. B) lags the voltage by 90^$\circ$. C) is in phase with the voltage. D) leads the voltage by $\pi$ radians. E) lags the voltage by $\pi$ radians.

Question

Quizplus · Accepted Answer

In an inductive circuit, the current lags the voltage by 90 degrees, or pi/2 radians. This is due to the fact that the inductor opposes changes in current, and takes time to build up a magnetic field, causing the current to lag behind the voltage.
