measured in amps, represents how fast the energy moves through a circuit. For example, you might use horsepower and voltage to find the current in a motor. In order to calculate the current from the horsepower and voltage, you must also know the efficiency of the circuit...
measured in volts, and the current I, measured in amps, passing through it. In mechanics, the definition of power is the rate of doing work W. It's defined as W/t, where t is the time it takes for the work to be completed....
Calculate three-phase motor power consumption by multiplying amps by volts by the square root of three (W = AV(sqrt 3). For example, if the motor is drawing 30 amps at 250 volts, you have 30 x 250 x sqrt 3 (about 1.73) = 12,975 watts). Convert watts to kilowatts by dividing th...
