what is reactive power


is it good or bad for a system

Answer Posted / shyamkr

reactive power is that component of apparent power which
moves to and fro between electrical source and energy
storing element.it doesn't do any useful work.it always
comes into action when there is reactive or energy storing
element.
when a load of low power factor is used it draws a large
amount of reactive power due to which the current in the
circuit increases which causes more losses in the circuit.
