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
As a proper name
