  1. Question 1

    Q1. The power factor of a circuit is 0.5. The circuit is

    • A) Purely resistive
    • B) Purely inductive
    • C) Purely capacitive
    • D) R-L or R-C circuit

    Answer: R-L or R-C circuit

    Explanation: Power factor = cos(φ) = 0.5 implies φ = 60°. This is possible in R-L or R-C circuits.
