the electrostatic potential difference between the terminals of a circuit or battery when no current is flowing. Also called electromotive force.
(pronounced "ee em eff") a physical quantity which describes the ability of an electrical source to deliver energy. You can also think of it as the property of the source which creates current in a circuit. Derived from the nineteenth century term " lectro otive orce" which is ok (pronounced "okay") as far as the electromotive bit goes, but it is not a force as we define force now. The emf of a battery is responsible for producing a potential difference between the battery's terminals. If the battery is not connected to anything else, that potential difference is equal to the emf. The SI unit is the volt, symbol V. [Not to be confused with lectro agnetic ield which the popular press sometimes refers to as EMF.
Electro agnetic Frequency
Acronym for "electromotive force" See voltage.
the rate at which energy is drawn from a source that produces a flow of electricity in a circuit; expressed in volts
This is the common abbreviation for the electromotive force – the force that pushes electrons around a circuit. It can be supplied by a battery and is measured in units of volts. Rivers of Electrons
Electro Motive Force. The name given to the various mechanisms which produces a separation of positive and negative charge which ultimately leads to flow of charge
Electro Magnetic Fields. Invisible force fields that surround the movement of electricity.
Electromotive Force or voltage.
(see "electromotive force")
electromotive force. Symbol: E. Unit: volt. The property of electrical energy that causes a current to flow.
Electromotive force. A rise in (electrical) potential energy. The principal unit is the volt.
The force that causes electricity to flow between two points with different electrical charges or when there is a difference of potential between the two points. The unit of measurement is volts.
