It is defined as electromotive force, and the difference in electrical potential between 2 points in a circuit. It has also been explained as the pressure in an electrical circuit.

Electro-magnetism, or the electromotive force - EMF.

Voltage measures the electrical potential between two parts of an electrical circuit. Also called electromotive force. Voltage provides the 'pressure' to drive electrons round a circuit.

EMF (electromotive force) is more useful, in fact vital, for any electrical or electronic circuit. At school level your teacher would not make a distinction (and probably doesn't know the difference, or even realise there is one) between electromotive force and potential difference. In answer to a school question, it's potential difference.

'Voltage' is simply another term for 'potential difference', and an electromotive force is the open-circuit, or no-load, potential difference of a source such as a battery or generator.

An electromotive force or potential difference between its ends.

Voltage (of a circuit) as defined in the NEC: n. The greatest root-mean-square(rms) (effective) difference of potential between any two conductors of the circuit concerned. Voltage as defined by Webster's: n. Electromotive force or potential difference, usually expressed in volts.

Voltage measures the electrical potential between two parts of an electrical circuit. Also called electromotive force. Voltage provides the 'pressure' to drive electrons round a circuit.

An electromotive force is the potential differenceappearing across the terminals of a battery, generator, etc., when that device is not supplying any load. When the device is supplying a load current, the electromotive force is equal to the sum of the voltage drops around the complete circuit, including any internal voltage drop.A potential difference (also known as a 'voltage'), as the name implies, is the difference in potential between two points.

A voltmeter is used to measure the difference in electric potential ("voltage") between two points, usually but not necessarily in an electrical circuit..
