REAL POWER

The component of apparent power delivered that is useful and actually does the work. It flows from source to load and is totally used by the load. Example: the Apparent Power necessary to turn a motor at a specific speed and torque consists of the Real Power (contributes to speed and torque) and the Reactive power (energizes the motor coil, but does not contribute to speed or torque. Real power is calculated by multiplying current times voltage times true power factor. (Pwatts = I x V x FPtrue) Power losses in wires can be calculated by squaring the rms current and multiplying by the resistance. (Pwatts = I2rms x R). Real Power is measured in watts, or kilowatts; abbreviated “W” or “kW”. (see: Volt Amp; Current; Power Factor; Apparent Power; Ohm’s Law; Reactive Power; Watt)
