STANDARD Physics Resonance in LCR Circuits MCQ Question
Type: MCQ-numerical-Medium-Class 12
The resonant frequency of a series LCR circuit with L = 2.0 H, C = 32 μF and R = 10 Ω is
A
20 Hz
B
30 Hz
C
40 Hz
D
50 Hz
Correct Answer
Option A
Detailed Explanation
The resonant frequency is given by ω₀ = 1/√(LC). Substituting L = 2 H and C = 32 × 10⁻⁶ F, we get ω₀ = 125 rad/s. Converting to Hz, v₀ = ω₀/2π = 20 Hz.
