Question

Define electromotive force. . . . .​

Answer 1

Answer:

Explanation:

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.

A few of the examples of electromotive force include Electro chemical cells, thermo electric devices, solar cells, electrical generators, transformers, etc. Electro chemical cells: It is a device which is capable of producing electrical energy through chemical reactions.

Answer 2

In electromagnetism and electronics, electromotive force is the electrical action produced by a non-electrical source. Devices provide an emf by converting other forms of energy into electrical energy, such as batteries or generators. Sometimes an analogy to water pressure is used to describe electromotive force
