Power factor — For other uses, see Power factor (pistol). The power factor of an AC electric power system is defined as the ratio of the real power flowing to the load over the apparent power in the circuit,[1][2] and is a dimensionless number between 0 and 1… … Wikipedia
Efficiency — as a technical term may refer to: * Algorithmic efficiency, optimizing the speed and memory requirements of a computer program * Efficient energy use, useful work per quantity of energy ** Energy conversion efficiency, desired energy output per… … Wikipedia
Power scaling — of a laser is increasing its output power without changing the geometry, shape, or principle of operation. Power scalability is considered an important advantage in a laser design.Usually, power scaling requires a more powerful pump source,… … Wikipedia
Power supply — For the Budgie album, see Power Supply (album). A vacuum tube rackmount adjustable power supply, capable of +/ 1500 volts DC, 0 to 100mA output, with amperage limiting capability. A power supply is a device that supplies electrical energy … Wikipedia
Power MOSFET — A Power MOSFET is a specific type of Metal Oxide Semiconductor Field Effect Transistor (MOSFET) designed to handle large power. Compared to the other power semiconductor devices (IGBT, Thyristor...), its main advantages are high commutation speed … Wikipedia
Power station — A power station (also referred to as generating station, power plant or powerhouse) is an industrial facility for the generation of electric power. [cite book|author=British Electricity International|title=Modern Power Station Practice:… … Wikipedia
Maximum power transfer theorem — In electrical engineering, the maximum power transfer theorem states that, to obtain maximum external power from a source with a finite internal resistance, the resistance of the load must be equal to the resistance of the source as viewed from… … Wikipedia
Maximum power theorem — In electrical engineering, the maximum power (transfer) theorem states that, to obtain maximum external power from a source with a finite internal resistance, the resistance of the load must be made the same as that of the source. It is claimed… … Wikipedia
thermoelectric power generator — Introduction any of a class of solid state devices (solid state device) that either convert heat directly into electricity or transform electrical energy into thermal power for heating or cooling. Such devices are based on thermoelectric… … Universalium
