	Electromotive force - Wikipedia, the free encyclopedia
		The term "electromotive force" originally referred to the 'force' with which positive and negative charges could be separated (i.e.
		moved, hence "electromotive"), and was also called "electromotive power" (although it is not a power in the modern sense).
		Oxford English Dictionary, "electromotive force".) The term is attributed to Alessandro Volta.

	Electric voltage
		When a voltage is generated by a battery, or by the magnetic force according to Faraday's Law, this generated voltage has been traditionally called an "electromotive force" or emf.
		It is useful to distinguish voltages which are generated from the voltage changes which occur in a circuit as a result of energy dissipation, e.g., in a resistor.
		The magnetic force exerted on the charges in a moving conductor will generate a voltage (a motional emf).

		It is defined as the difference of electric potential existing across the ends of a conductor carrying a constant current of 1 ampere when the power dissipated is 1 watt.
		Electromagnetic induction is the production of an electromotive force (emf) in a conductor as a result of a changing magnetic field about the conductor and is the most important of the three phenomena.
		Lenz's law LENZ'S LAW [Lenz's law] physical law, discovered by the German scientist H. Lenz in 1834, that states that the electromotive force (emf) induced in a conductor moving perpendicular to a magnetic field tends to oppose that motion.

	Electromotive force
		Students, when dealing with electric circuits, often have difficulty in understanding the distinction between potential difference (PD) and electromotive force (EMF).
		Yet it is important to understand this distinction, which occurs in several situations: the potential difference at the terminals of a battery may be less than its EMF.
		In the author's experience, any difficulty usually arises from a misunderstanding of the nature of electromotive force rather than a failure to understand the nature of potential difference.

	Electromotive Force (EMF)
		The electromotive force (EMF) is the maximum potential difference between two electrodes of a galvanic or voltaic cell.
		This quantity is related to the tendency for an element, a compound or an ion to acquire (i.e.
		has been measured to be 1.100 V. A concentration of 1 M in an ideal solution is defined as the standard condition, and 1.100 V is thus the standard electromotive force,

		Define voltage - a definition from Whatis.com - see also: electromotive force
		Voltage, also called electromotive force, is a quantitative expression of the potential difference in charge between two points in an electrical field.
		The greater the voltage, the greater the flow of electrical current (that is, the quantity of charge carriers that pass a fixed point per unit of time) through a conducting or semiconducting medium for a given resistance to the flow.
