Electromotive force

The electromotive force (e.m.f.) is the very force that moves the electrons from one point in an electric circuit towards another. The greater the electromotive force, the greater the pressure on the electrons moving through the conductor. A battery or the other source of an electromotive force is simply a device that produces a potential difference necessary for causing electric current to flow along a conductor. We know the current to flow through a conductor in case there is a potential difference between the ends of the conductor.

The e.m.f. is measured and the volt is the unit in which it is measured.

One should distinguish between an electromotive force and a potential difference. A generator or battery is a source of electromotive force, whereas the voltage across a resistance in which a current is flowing is a potential difference or voltage drop. The e.m.f. of a battery or a generator cannot be measured exactly at its terminals since these devices have an internal voltage drop when the circuit is completed.

If an e.m.f. is applied to a path which allows the electrons to pass, they will move toward the point of higher potential, and then current flows in the circuit.

In a closed circuit consisting of a source of e.m.f., of metallic conductors and a device, the electric current is flowing from a plus terminal of a source of e.m.f. to minus terminal, giving up its energy in the form of heat.

When the current flows through a source of e.m.f. in the direction in which the e.m.f. tends to produce current, energy is transferred from the source of e.m.f. to the circuit. Quite the opposite, the current flowing against the e.m.f., energy is transferred from the circuit to the source of e.m.f.

 

Пояснения к тексту:

the very – тот самый

in case – в случае, если

coulomb – кулон

one should distinguish – следует различать

in general – вообще

quite the opposite – наоборот

to give up energy – отдавать энергию

unit – единица (измерения)
