List of top Electric circuits Questions on AC power, power factor with non-sinusoidal waveforms asked in GATE EE

A single-phase voltage source \(v_s=325\sin(2\pi 50t)\) V delivers a current, \(i=12\sin(2\pi 50t)+9\sin(2\pi 150t)\) A to a load.
The load power factor, correct up to two decimal places, is:
