Power source
Appearance
A power source is a source of power. Most commonly the type of power referred to is:
- Power (physics), the rate of doing work; equivalent to an amount of energy consumed per unit time
- Electric power, the rate at which electrical energy is transferred by an electric circuit; usually produced by electric generators or batteries
Power source may correspondingly refer to:
- A source of primary energy, an energy form found in nature that has not been subjected to any conversion or transformation process
- Energy carrier, or secondary energy, a substance or phenomenon that contains energy that can be later converted to other forms such as mechanical work or heat or to operate chemical or physical processes
- Fuel, a material that stores potential energy in forms that can be practicably released and used for work
- See Energy development for an overview of primary and secondary energy or power sources
or, often more specifically to an electric power source:
- The electric power industry
- A source of electrical energy
- Electric power system, a network of electrical components used to supply, transmit and use electric power
- Electricity generation, the process of generating electric power from other sources of primary energy
- Power station, an industrial facility for the generation of electric power
- Electric generator, a device that converts mechanical energy to electrical energy for use in an external circuit
- Electric power transmission
- Electric power distribution
- Mains electricity or household power, the general-purpose alternating-current (AC) electric power supply
- AC power plugs and sockets, devices that allow electrically operated equipment to be connected to the primary alternating current (AC) power supply in a building
- Battery (electricity), a device consisting of one or more electrochemical cells that convert stored chemical energy into electrical energy
- Electric power system, a network of electrical components used to supply, transmit and use electric power
Some conversion devices are sometimes called a "power source":
- Engine, a machine designed to convert energy into useful mechanical motion
- Power supply, an electrical device that supplies electric energy to an electrical load, by converting one form of electrical energy to another
As a proper name
[edit]PowerSource may also refer to:
- PowerSource (phone brand), mobile phone that can make use of both Sprint-Nextel cellular networks
- PowerSource (musical group), a Christian music group of the 1980s
- PowerSource, a weekly print section, and a companion website of the Pittsburgh Post-Gazette, highlighting the Pittsburgh region’s diverse energy industry
