  1. Question 1

    Q1. An inductor of inductance 0.1 H is connected to an AC source of frequency 50 Hz. What is the inductive reactance?

    • A) 31.4 Ω
    • B) 15.7 Ω
    • C) 62.8 Ω
    • D) 3.14 Ω

    Answer: 31.4 Ω

    Explanation: Xl = 2πfL = 2π x 50 x 0.1 = 31.4 Ω. Option B is wrong due to miscalculation.
