electromotive force

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. : emf, EMF, E.M.F., e.m.f.

electromotive force

physics
1. a source of energy that can cause a current to flow in an electrical circuit or device
2. the rate at which energy is drawn from this source when unit current flows through the circuit or device, measured in volts AbbreviationemfEMF E Compare potential difference

electromotive force

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.

First recorded in 1825–35

Rusty lead, so to speak, so connected with bright lead, has a high electromotive force.

Now whenever an electric conductor cuts magnetic lines of force an electromotive force is induced in the conductor.

If the coils are rotated in a magnetic field, each will produce an electromotive force.

Electromotive Force, the name given to the force tending to produce a flow of electricity in an electric circuit.

For a discussion of the electromotive force produced by thermo-electric action, see Thermo-electricity.
