An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. An example of a power system is the that provides power to homes and industries within an extended area. The electrical grid can be broadly divided into the that supply the power, the that carries the power from the generating.

[pdf] Micropower describes the use of very small electric generators and prime movers or devices to convert heat or motion to electricity, for use close to the generator. The generator is typically integrated with microelectronic devices and produces "several watts of power or less." These devices offer the promise of a. .

[pdf] Electric power is the product of two quantities: and . These two quantities can vary with respect to time () or can be kept at constant levels (). Most refrigerators, air conditioners, pumps and industrial machinery use AC power, whereas most computers and digital equipment use DC power (digital devices plugged into the mains typically have an internal or external to convert from AC to DC power). AC power has the a.
