  1. Question 1

    Q1. In an AC circuit, the voltage and current are in phase when the circuit contains only

    • A) Resistance
    • B) Inductance
    • C) Capacitance
    • D) Impedance

    Answer: Resistance

    Explanation: In a purely resistive circuit, voltage and current are in phase; 'Inductance' or 'Capacitance' causes a phase shift.
