  1. Question 1

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

    • A) 31.83 ohms
    • B) 318.3 ohms
    • C) 3.183 ohms
    • D) 3183 ohms

    Answer: 31.83 ohms

    Explanation: X_C = 1/(2πfC) = 1/(2 * 3.14 * 50 * 100 * 10^(-6)) = 31.83 ohms. Option B is incorrect due to wrong calculation.
