Question

A voltage V = Vo sin wt applied to a series LCR

circuit drives a current i = io sin wt in the circuit.

Deduce the expression for the average power

dissipated in the circuit.

For circuits used for transporting electric power,

a low power factor implies large power loss in

transmission. Explain.
