Power source

From Wikipedia, the free encyclopedia

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:

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
