  1. Question 1

    Q1. A capacitor is connected to an AC source with a frequency of 50 Hz. If the capacitance is 10 μF, what is the capacitive reactance?

    • A) 159 Ω
    • B) 318 Ω
    • C) 637 Ω
    • D) 1000 Ω

    Answer: 318 Ω

    Explanation: Xc = 1 / (2πfC) = 1 / (2π * 50 Hz * 10e-6 F) = 318 Ω. Option A is incorrect because it is half the correct value.
