Question

In the case of an inductor

• A. voltage lags the current by $ \frac {\pi}{2} $
• B. voltage leads the current by $ \frac {\pi}{2} $
• C. voltage leads the current by $ \frac {\pi}{3} $
• D. voltage leads the current by $ \frac {\pi}{4} $

Answer 1

Answer: (B)

In an inductor voltage leads the current by $\frac {\pi}{2}$ or current lags the voltage by $\frac {\pi}{2}$
