  1. Question 1

    Q1. A capacitor of 10 μF is connected to an AC supply of 100V, 50Hz. What is the reactance?

    • A) 318 ohm
    • B) 159 ohm
    • C) 3180 ohm
    • D) 1590 ohm

    Answer: 318 ohm

    Explanation: Capacitive reactance Xc = 1 / (2 * π * f * C) = 1 / (2 * 3.14 * 50 * 10 * 10^(-6)) = 318 ohm.
