  1. Question 1

    Q1. The voltage across an inductor is 100 V, 50 Hz. If L = 0.1 H, what is the current?

    • A) 3.18 A
    • B) 1.59 A
    • C) 6.37 A
    • D) 0.318 A

    Answer: 3.18 A

    Explanation: Use XL = 2πfL and I = V / XL: XL = 2 * 3.14 * 50 * 0.1 = 31.4, I = 100 / 31.4 = 3.18 A.
