  1. Question 1

    Q1. A pure inductor is connected to an AC source. What is the power consumed?

    • A) Maximum
    • B) Zero
    • C) Half of maximum
    • D) None of these

    Answer: Zero

    Explanation: In a pure inductor, the current lags the voltage by π/2, so the power factor = cos(π/2) = 0, hence power consumed = 0.
