A series LCR circuit is connected to a 220 V variable frequency (a.c) supply. If $L = 20mH, C = (\frac{800}{π^2}) µF$ and $R = 110 Ω$. The frequency of the source, for which the average power absorbed by the circuit is maximum will be: |
125 Hz 250 Hz 350 Hz 500 Hz |
125 Hz |
The correct answer is Option (1) → 125 Hz |
