NEET 2023 Physics LCR Circuits MCQ Question
In a series LCR circuit, the inductance L is 10 mH, capacitance C is 1 μF and resistance R is 100 Ω. The frequency at which resonance occurs is :
15.9 kHz
1.59 rad/s
15.9 kHz
15.9 rad/s
Correct Answer
Detailed Explanation
The resonance frequency in a series LCR circuit is given by f = 1/(2π√(LC)). Substituting L = 10 mH = 10^-2 H and C = 1 μF = 10^-6 F, we get f = 1/(2π√(10^-2 * 10^-6)) = 15.9 kHz.
