  1. Question 1

    Q1. A capacitor of 2 μF is connected to an AC source. If the reactance is 100 Ω, what is the frequency?

    • A) 795.77 Hz
    • B) 1591.55 Hz
    • C) 3183.1 Hz
    • D) 6366.2 Hz

    Answer: 795.77 Hz

    Explanation: Use Xc = 1 / (2πfC): f = 1 / (2π * 100 * 2e-6) = 795.77 Hz.
