  1. Question 1

    Q1. An inductor of 0.5 H is connected to an AC source. If current is 2 A and voltage is 200 V, find frequency.

    • A) 31.83 Hz
    • B) 50 Hz
    • C) 100 Hz
    • D) 200 Hz

    Answer: 31.83 Hz

    Explanation: Use V = I * Xl, where Xl = 2πfL. So, f = V / (2πIL) = 200 / (2π * 2 * 0.5) = 31.83 Hz.
