Question

An AC voltage is applied to a pure inductor $L$, drives a current in the inductor. The current in the inductor would be

• A. ahead of the voltage by $ \pi /2 $
• B. lagging the voltage by $ \pi /2 $
• C. ahead of the voltage by $ \pi /4 $
• D. lagging the voltage by $ 3\pi /4 $

Answer 1

Answer: (B)

For an inductive circuit (L-circuit) voltage leads the current by $ \frac{\pi }{2} $ .
