Bhautik Study.

A series LCR circuit containing 5 H inductor 80μF capacitor and 40 Ω resistor is connected to 230V variable frequency AC source. The angular frequencies of the source at which power transferred to the circuit is half the power at the resonant angular frequency are likely to be (1) 25 rad/s and 75 rad/s (2) 50 rad/s and 25 rad/s (3) 46 rad/s and 54 rad/s (4) 42 rad/s and 58 rad/s
