At alternating voltage is applied across the R-L combination V =220 sin 120t V and the current I = 4sin (120t - 60^@ )A developes. The power consumption is ……

An alternating voltage V = V_(0) sin omegat is applied across a circuit. As a result, a current I = I_(0) sin (omegat – p/2) flows in it. The power consumed per cycle is

In an AC circuit the voltage applied is E = E_(0) sin omega t . The resulting current in the circuit is I = I_(0) sin (omega t - (pi)/(2)) . The power consumption in the circuit is given by
