Answer / n panja
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.

defination w.r.t ps:-
It is the power needed by the transmission line to transfer
active power from one point to another point.This means
without reactive power,active power can"t be transferred.

Answer / pramila raj
The power value obtained by multiplying together the effective value of current in amperes, the effective value of voltage in volts, and the sine of the angular phase difference between current and voltage. Also known as wattless power.
