  1. Question 1

    Q1. The power factor of a circuit is 1. The circuit is

    • A) purely resistive
    • B) purely inductive
    • C) purely capacitive
    • D) resonant

    Answer: purely resistive

    Explanation: Power factor = 1 implies cos(φ) = 1, so φ = 0; the circuit is purely resistive.
