  1. Question 1

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

    • A) 10 Ω
    • B) 100 Ω
    • C) 1000 Ω
    • D) 10000 Ω

    Answer: 1000 Ω

    Explanation: The capacitive reactance is given by Xc = 1 / (2πfC), so it's 1 kΩ, but the closest answer is 1000 Ω, not 10 Ω, 100 Ω, or 10000 Ω.
