Reactive power effect on voltage
WebMay 14, 2007 · Reactive power is the power stored in capacitors and or inductors. The capacitive or industive loads cause a lead and lag between the load voltage and curent. The cosine of this agle is called the power factor. A power factor of less than 1 reduce the usagfull wattage (enegy) of the supply.
