Question
A sinusoidal voltage is applied to a series RLC circuit with L=10.0 mH, C=100 nF, R=20.0 Ω. Resonant frequency?
Correct Answer
Option B is the correct answer.
Detailed Explanation
f = 1/(2π√(LC)) = 1/(2π√(0.01 × 100×10⁻⁹)) = 1/(2π√(1×10⁻⁹)) = 1/(2π×3.16×10⁻⁵) = 1/(1.986×10⁻⁴) = 5033 Hz.
Hint
f = 1/(2π√(LC)).
