Question

Derive the expression for the average power consumed in series LCR a.c. circuit.

Answer 1

Power consumed in a Series LCR Circuit. Total work done over a complete cycle is obtained by integrating above equation from 0 to T. Hence, average power over a complete cycle in an inductive circuit is the product of virtual e.m.f., virtual current and cosine of the phase angle between the voltage and the current.
