Voltage (noun)

1. An electrical force or potential difference, expressed in volts, that exists between two points in a circuit and drives the flow of electric current.
2. A difference in electric potential that arises between two points in a circuit, especially as a result of a current flowing through the circuit.

Origin:

Late 19th century: from french voltage, from volter "to turn", from latin volvere.

Examples:

1. The voltage between the two points was measured in volts.
2. The voltage increased as the current flowed through the circuit.
3. The voltage caused the electric current to flow.
4. The voltage was measured using a voltmeter.
5. The voltage was too high and needed to be reduced.
