NEET Physics AC Voltage MCQ Question
In a series LCR circuit with L = 0.12 H, C = 480 nF, and R = 23 Ω connected to a 230 V variable frequency supply, what is the source frequency at which the average power absorbed by the circuit is maximum?
1/(2π√(LC))
1/(2πRC)
1/(2π√(L/C))
1/(2π√(R/L))
Correct Answer
Detailed Explanation
The average power absorbed by the circuit is maximum at the resonant frequency, which is given by 1/(2π√(LC)) as per the NCERT context.
