NEET 2023 Physics LCR Circuits MCQ Question
Type: MCQ-numerical-Medium-Class 12
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 :
A
15.9 kHz
B
1.59 rad/s
C
15.9 kHz
D
15.9 rad/s
Correct Answer
Option A
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.
