question

is there a difference in power between the power input and power output
passage · full text (634 characters)
Equipment is generally rated by the power they will deliver, for example, at the shaft of an electric or hydraulic motor. The power input to the equipment will be greater owing to the less than 100% efficiency of the device. Efficiency of a device is often defined as the ratio of output power to the sum of output power and losses. In some types of equipment it is possible to measure or calculate losses directly. This allows efficiency to be calculated with greater precision than the quotient of input power over output power, where relatively small measurement uncertainty will greatly affect the resulting calculated efficiency.
