  1. Question 1

    Q1. Why is the power factor of an inductive circuit less than 1?

    • A) Current lags voltage, causing wasted energy.
    • B) Inductors consume reactive power permanently.
    • C) Voltage peaks before current completes a cycle.
    • D) Inductive reactance increases resistance.

    Answer: Current lags voltage, causing wasted energy.

    Explanation: Lagging current results in out-of-phase power. B is incorrect because reactive power is not lost but oscillates.
