how and why are capacitors are used to improve powerfactor?
Answer Posted / 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.
