WebPower factor (PF) is the ratio of working power, measured in kilowatts (kW), to apparent power, measured in kilovolt amperes (kVA). Apparent power, also known as demand, is the measure of the amount of power used to run machinery and equipment during a certain period. It is found by multiplying (kVA = V x A). The result is expressed as kVA units. WebThe mathematical equation that defines power is: Power ( in watts) = energy (in joules) over time (in seconds) or P = E over I or Energy (in joules, J) = power ( in watts, W) x time ( in seconds, s) or E = Pt What is a kilowatt-hour?
