Power source

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

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

Power source may also 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 two or more electrochemical cells that convert stored chemical energy into electrical energy

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

Usage examples of "power source".

In a very elaborate Buddhist mandala, for example, you have the deity in the center as the power source, the illumination source.

By helping you breathe more, I will help you reconnect with your power source.

At the same time that the microlasers disengage, the field's power is turned on, and electrical power is fed into the field from whatever power source is providing die necessary energy for the effect's maintenance.
