Inductive Circuit Power Factor. In pure inductive circuit or capacitive circuit where voltage is leading by 90 from current and current is leading 90 from voltage respectively. For the purely resistive circuit the power factor is 1 perfect because the reactive power equals zero.
In such cases active or passive power factor correction may be used to counteract the distortion and raise the power factor. As we calculate above that true power is equal to 720 watt and the apparent power is equal to 1018 va. Active real or true power is measured in watts w and is the power drawn by the electrical resistance of a system doing useful work.
Linear loads with low power factor can be corrected with a passive network of capacitors or inductors.
Apparent power is measured in volt amperes va and is the voltage on an ac system multiplied by all the current that flows in it. The loads such as induction motors coils lamps etc are inductive and have lagging pf. For the purely resistive circuit the power factor is 1 perfect because the reactive power equals zero. Lagging power factor when current lags behind the voltage the power factor of the circuit is called lagging when the circuit is inductive the pf is lagging.
