Question

In a pure inductive circuit, current

• A. lags behind emf by $ \frac{\pi }{2} $
• B. leads the emf by $ \frac{\pi }{2} $
• C. lags behind by $ \pi $
• D. leads the emf by $ \pi $

Answer 1

Answer: (A)

In a pure inductive circuit, current lags behind the emf by $\frac{\pi}{2}$ or $90^{\circ}$.
