Power
Power is the amount of energy consumed or produced over time.
- Power is a measurement of the energy used to move vehicles (automobiles, trucks, tractors, trains, boats and airplanes).
- Power is the measurement of energy consumed by a motor and transferred to the drive or wheels.
- Power is the amount of electrical energy consumed or produced by a system over time such as the energy produced by a hydroelectric dam or energy consumed by an electrical motor.
Power Units
Power is most commonly measured in watts (W). One watt is equal to one joule per second (1 W = 1 J / 1 s). Power is also measured in horsepower (hp) where 1 horsepower equals 745.7 watts. Power is also measured in heat energy transfer as BTUs per hour (BTU/h).
