  1. Question 1

    Q1. A coil has an inductance of 0.2 H. When connected to an AC source of 50 Hz, what is its inductive reactance?

    • A) 62.8 ohms
    • B) 31.4 ohms
    • C) 125.6 ohms
    • D) 628 ohms

    Answer: 62.8 ohms

    Explanation: X_L = 2πfL = 2 * 3.14 * 50 * 0.2 = 62.8 ohms. Option B is incorrect due to wrong calculation.
