NEET Physics AC Voltage MCQ Question
In a series LCR circuit with L = 0.12 H, C = 480 nF, R = 23 Ω connected to a 230 V variable frequency supply, what is the resonant frequency of the circuit?
650.0 Hz
500.0 Hz
600.0 Hz
450.0 Hz
Correct Answer
Detailed Explanation
The resonant frequency of a series LCR circuit is given by . Substituting L = 0.12 H and C = 480 nF, we calculate the resonant frequency to be approximately 650.0 Hz.
