Power factor formula: Power factor is defined as the ratio

Power factor is defined as the ratio of real power to the apparent power. The formula for the power factor is given below : Real Power - The capacity of the electricity for performing work. It is also known as true power, active power, and working power. It is measured in kilowatts (kW). Learn how to calculate power factor , a ratio between true power and apparent power , using a power triangle. See how to improve power factor by adding a capacitor in parallel to an inductive load. In simple terms, power factor is the ratio of useful power (real power) doing actual work to the total power supplied (apparent power). P F = Real Power (kW) Apparent Power (kVA) = cos (θ) Power factor is defined as the cosine of angle between the voltage phasor and current phasor in an AC circuit. It is denoted as pf. For an AC circuit, 0≤pf≤1 whereas for DC circuit power factor is always 1. It can be calculated by calculating the ratio of Active Power and Apparent Power .
