Question

Choose the wrong statement for the pure inductive circuit.

• A. The inductive reactance limits the current in a purely inductive circuit
• B. The average power supplied to an inductor over one complete cycle is zero
• C. The inductive reactance is directly proportional to the frequency of the current
• D. The emf of the source and current oscillates symmetrically about zero value
• E. The current leads the voltage by $\pi /2$

Answer 1

Answer: (E)

Current lags the voltage by $\pi /2$.
