Power is the rate at which work is done, or in equation form, for the average power P for work W done over a time t, P=W/t. The SI unit for power is the watt (W), where \(1 \space W ...Power is the rate at which work is done, or in equation form, for the average power P for work W done over a time t, P=W/t. The SI unit for power is the watt (W), where 1W=1J/s. The power of many devices such as electric motors is also often expressed in horsepower (hp), where 1hp=746W.
