Answer 1

Right choice is (c) (I^2maxR)/2 The explanation is: The upper and lower cut-off frequencies are sometimes called the half-power frequencies,. At these frequencies the power from the source is half of the power delivered at the resonant frequency. The expression of power (P1) at lower half power frequency is P1 = (I^2maxR)/2.
