Reactive power is the part of total electric power supplied
by the sources (alternating) which travels in the circuit
back and forth without doing any useful work. This power can
not be extracted or converted into other form of energy.
That is why it is also called wattless power. The average
value of reactive power over a full cycle for a sinusoidal
source is zero. Unit of reactive power is VAr.

WE know that for Inductor X=2pifL,In DC f=0,then X=0 so,V=IX=0;But In the DC excitation of rotor of AC generator,DC motor field coil which coils are inductor so why does not applying DC voltage short the rotor coil of AC generator and field coil of motor?If it would then DC source might be damaged but it is not happened. Why does the strand conductor of Electrical power transmission line make twist?
