  1. Question 1

    Q1. An AC circuit contains a resistor and an inductor. What happens to the current when the frequency of the supply is increased?

    • A) Current increases due to decreased impedance
    • B) Current decreases due to increased impedance
    • C) Current remains the same
    • D) Current becomes DC

    Answer: Current decreases due to increased impedance

    Explanation: Higher frequency increases inductive reactance and impedance.
