  1. Question 1

    Q1. A capacitor is connected to an AC source. What happens to its capacitive reactance when the frequency is doubled?

    • A) It becomes half
    • B) It becomes double
    • C) It remains the same
    • D) It becomes zero

    Answer: It becomes half

    Explanation: Capacitive reactance is inversely proportional to frequency; doubling frequency halves reactance. Option B is incorrect because reactance decreases, not increases.
