noun Electricity.
- the energy available for conversion from nonelectric to electric form, or vice versa, per unit of charge passing through the source of the energy; the potential difference between the terminals of a source of electrical energy: expressed in volts. Abbreviation: emf
noun
- physics
- a source of energy that can cause a current to flow in an electrical circuit or device
- the rate at which energy is drawn from this source when unit current flows through the circuit or device, measured in voltsAbbreviation: emf, EMF Symbol: E Compare potential difference
n.
- The energy per unit charge that is reversibly converted from chemical or other forms of energy into electrical energy in a battery.
- Electric potential or voltage. Electromotive force is not really a force, but a measure of how much work would be done by moving an electric charge.
