  • Power Factor - Inductive Load - Engineering ToolBox

    The power factor of an AC electric power system is defined as the ratio active (true or real) power to apparent power, where. Active (Real or True) Power is measured in watts (W) and is the power drawn by the electrical resistance of a system doing useful work; Apparent Power is measured in volt-amperes (VA) and is the voltage on an AC system multiplied by all the current that flows in it.
