a source of energy that can cause a current to flow in an electrical circuit or device
b.
the rate at which energy is drawn from this source when unit current flows through the circuit or device, measured in volts
Abbreviation: emf, EMF. Symbol: E. Compare potential difference
electromotive force in American English
the force or electric pressure that causes or tends to cause a current to flow in a circuit, equivalent to the potential difference between the terminals and commonly measured in volts
abbrev. E, EMF, or emf
electromotive force in Electrical Engineering
(ɪlɛktroʊmoʊtɪv fɔrs) or EMF
noun
(Electrical engineering: General)
Electromotive force is voltage, or the difference in the electric tension or the difference in charge between two points that causes an electric current.
The potential difference between two points of a conductor creates an electromotive force which pushes free electrons in a conducting material to move towards the positiveterminal, creating current.
This varying magnetic field induces a varying electromotive force or "voltage" in the secondary winding.
Electromotive force is voltage, or the difference in the electric tension or the difference in chargebetween two points that causes an electric current.
