  1. Question 1

    Q1. The impedance of an AC circuit is given by Z = √(R² + X²), where X is the reactance. For a capacitor, X is

    • A) 1 / ωC
    • B) ωC
    • C) ωL
    • D) 1 / ωL

    Answer: 1 / ωC

    Explanation: Capacitive reactance Xc = 1 / ωC, where ω = 2πf, used in impedance calculation.
