  1. Question 1

    Q1. The power factor of an AC circuit is 0.5. The circuit contains

    • A) only resistance
    • B) resistance and inductance
    • C) resistance and capacitance
    • D) only inductance

    Answer: resistance and inductance

    Explanation: Power factor = cosφ = R/Z = 0.5, indicating the presence of both resistance and reactance (inductive).
