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)

lagging the voltage by $\pi /2$

Answer 2

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