Active power is that power which is used for useful work
and reative power is used for producing magnetic flux for
rotating electrical machines.Explanation by simple example:-
if we want to go from Delhi to Mumbai by plane. If plane is
flying at 3 kms height (vertical height) it is reactive
power and horizontal distance(from Delhi to Mumbai)it is
called active power or useful power.

Answer / indranil banerjee

Reactive power is that component of power for which we
don't pay any money, but we put our own system to a
pressure.

It is like somebody climbing upstairs and coming down
without doing anything.
