A power factor of a circuit can be improved by placing which, among the following, in a circuit?(a) Inductor(b) Capacitor(c) Resistor(d) SwitchI have been asked this question in an internship interview.My enquiry is from Capacitance topic in chapter Capacitance and Capacitors of Basic Electrical Engineering
Answer» Correct CHOICE is (b) CAPACITOR Best explanation: Power factor = Real power/Apparent power = KW/kVA By adding a capacitor in a circuit, an additional kW load can be added to the SYSTEM WITHOUT altering the kVA. Hence, the power factor is improved.
