A measure of how efficiently electrical powerThe rate of transfer of energy. It’s essentially how quickly… is being used. It shows how much of the total power flowing in a circuit is actually doing useful work (active powerAlso known as real or true power, is the portion of electric…) versus being ”wasted” as reactive powerPower that does not perform useful work but is used to estab…. A power factor closer to 1 means higher efficiency and fewer losses.
