Answer / gunasekhar
power factor poor means current is lagged behind voltage . capacitor has leading current. it compensates the phase angle between voltage and current when we connect capacitor.

Answer / guest
Generally, poor power facor means that the current lag
behind voltage because of inductive loads. Capacitors
supply leading current with respect to the voltage which
cancels out the effect of inductive loads. Thus the source
side views the loads as purely resistive one. ence,
capacitors are used to improve power factor

Answer / d.ramesh clsses
follow the answer#1 and you know, in capacitor the current has 90 degrees triangle forward than voltage and in inductors' current is 90 degrees backward than voltage, so because all motors are likes inductors because of theirs winding so capacitance reduces the angle between current and voltage and cause higher power factor and less energy consuming and high efficiency.
