		electromotive force, emf
voltage - the difference in electrical charge between two points in a circuit expressed in volts
		electric potential, potential, potential difference, potential drop

voltage (Noun)
The amount of electrostatic potential between two points in space.

voltage (n.)
Electric potential or potential difference, expressed in volts.

voltage
The amount of electrostatic potential between two points in space. Unit: volt.

voltage
Potential difference or electro-motive force expressed in volts; as a voltage of 100 volts. Thus voltage may express the electro-motive force absorbed in a conductor, while electro-motive force is a term generally applied where it is produced, evolved or present in the object. The term voltage of a lamp expresses simply the volts required, but does not suggest the possession of electromotive force.
Voltage, Terminal. The voltage or potential difference at the terminals of an electric current generator, such as a dynamo, as distinguished from the total electro-motive force of the dynamo or generator.
In batteries the distinction is not generally made in practice; the total electro-motive force of the battery is made the basis of calculations.

Voltage is the change in electric potential (meaning potential energy per unit charge) between two positions.

It is measured in volts. It was named after an Italian physicist Alessandro Volta who made the first chemical battery. Because it is similar in spelling with voltage, some scientists had made suggestions that it should be called "electric tension". Many other languages uses a word that means electric tension for voltage.

Mathematical definition.

Mathematically, the voltage is the amount of work needed to move a charge from one position to the other.

Measuring tools.

Some of the tools for measuring the voltage are the voltmeter, the potentiometer, and the oscilloscope. The voltmeter measures the current going through a fixed resistor, then the voltage can be found using Ohm's law. The potentiometer works by balancing the unknown voltage against the known voltage inside a ring created by two wires. The oscilloscope first increases voltage, then the oscilloscope uses the voltage to make the path of electrons bent. Then it uses the idea that the change in direction and the voltage are proportional to find the voltage.
