How Electrical Power Is Measured Brennan Electric

Electric power is the rate at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second. Standard prefixes apply to watts as with other SI units: thousands, millions and billions of watts are called kilowatts, megawatts and gigawatts respectively. A common misconception is that electric power is bought and sold, but actuall… WebElectrical power is calculated from P = potential difference x current = VI. The power, transferred to the motor from the power supply, is then expressed in joules/second or watts. In step 3, the efficiency of the energy transfer is calculated from.
