Define wattless current.

A circuit consisting of an inductance and a resistance joined to a 200 volt supply ( A.C.) It draws a current of 10 ampere. If the power used in the circuit is 1500 watt, then the wattless current component is

What do you mean by wattless current?

How does the wattless current conforms to the particle of energy conservation?

The r.m.s. current in an A.C. circuit is 4A. If the wattless current 2 sqrt(3)A , then the power factor of the circuit is

The r.m.s current in an AC circuit is 2A . If the wattless current be sqrt(3)A , what is the power factor?
