  1. Question 1

    Q1. A capacitor of capacitance 100 μF is connected to an AC source of 50 Hz. What is the capacitive reactance?

    • A) 31.85 ohm
    • B) 63.7 ohm
    • C) 15.9 ohm
    • D) 100 ohm

    Answer: 31.85 ohm

    Explanation: Xc = 1 / (2πfC) = 1 / (2 * 3.14 * 50 * 100 * 10^(-6)) = 31.85 ohm.
