Why are the copper losses in the line considerably less for a three-wire system?

What will be an ideal response?


The copper losses in the line are considerably less for a three-wire system for several reasons: the motor power is transmitted at a higher voltage requiring less current for a given load; the neutral carries no current when the two lighting circuits are balanced; and the copper losses are much less because less wire and current are required.
