question_answer
A coil has an inductance of 0.7 henry and is joined in series with a resistance of \[220\,\Omega \]. When the alternating emf of 220 V at 50 Hz is applied to it then the phase through which current lags behind the applied emf and the watt less component of current in the circuit will be respectively
