Power (P) is a measurement of work done in a unit of time. How much electricity is being consumed, which is power, in an electric circuit depends upon both the voltage and the current of the circuit. In electrical systems power is measured in watts (W) A watt is a measure of the energy produced or consumed in one second. Power is also commonly expressed in kW (1 kW = 1000 W) and MW (1 MW = 1,000,000 W) in larger systems. Similarly, if water flowing from the water system is used to perform work, like spinning a wheel, the power that is used will depend upon both the volume and the pressure of the water supplied. An inefficient load in an electrical system or water system requires more power to function than an efficient one.
