    Q1. The current in an AC circuit is wattless when the circuit contains only

    • A) Resistance
    • B) Inductance or capacitance
    • C) Impedance
    • D) Conductance

    Answer: Inductance or capacitance

    Explanation: Wattless current occurs in purely inductive or capacitive circuits; 'Resistance' does not cause wattless current.
