  1. Question 1

    Q1. A series LCR circuit has R = 10 Ω, L = 0.1 H, C = 100 μF. Find resonant frequency.

    • A) 50 Hz
    • B) 50 / π Hz
    • C) 50√2 Hz
    • D) 100 Hz

    Answer: 50 / π Hz

    Explanation: Resonant frequency f = 1 / (2π√(LC)), where L = 0.1 H and C = 100 μF, so f = 1 / (2π√(0.1 * 100 * 10^(-6))) = 50 / π Hz.
