In an `AC` circuit with voltage `V` and current `I`, the power dissipated is

In an a.c circuit with phase voltage V and current I, the power dissipated is

In an a.c. circuit, with phase voltage V and current I, the power dissipated is

If in an A.C. circuit voltage V and current is then the power dissipated in the circuit is …….

A 60 Hz AC voltage of 160 V impressed across an LR-circuit results in a current of 2A. If the power dissipation is 200 W, calculate the maximum value of the back emf (in volt) arising in the inductance.

What is the power dissipation in an AC circuit in which voltage and current are given by V = 300 sin (omegat +(pi)/(2)) and I = 5 sin omegat ?
