  1. Question 1

    Q1. In an LCR circuit, the resonance frequency is 1000 Hz. The capacitance is 100 μF. The inductance is

    • A) 0.25 mH
    • B) 0.025 H
    • C) 0.25 H
    • D) 0.025 mH

    Answer: 0.25 mH

    Explanation: f = 1 / (2π √(LC)), so L = 1 / ((2πf)²C) = 1 / ((2π * 1000)² * 100e-6) = 0.25 mH.
