  1. Question 1

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

    • A) 15.7 Ω
    • B) 31.4 Ω
    • C) 62.8 Ω
    • D) 125.6 Ω

    Answer: 31.4 Ω

    Explanation: Xl = 2πfL = 2π * 50 Hz * 0.1 H = 31.4 Ω. Option A is incorrect because it is half the correct value.
