Emf vs. Voltage

Emfnoun

(physics) EMF ("electromotive force")

Emfnoun

the rate at which energy is drawn from a source that produces a flow of electricity in a circuit; expressed in volts

Voltagenoun

(physics) The difference in electrostatic potential between two points in space, especially between live and neutral conductors or the earth.

Voltagenoun

Electric potential or potential difference, expressed in volts.

Voltagenoun

the rate at which energy is drawn from a source that produces a flow of electricity in a circuit; expressed in volts

Voltagenoun

the difference in electrical charge between two points in a circuit expressed in volts

Voltage

Voltage, electric potential difference, electromotive force (emf), electric pressure or electric tension is the difference in electric potential between two points, which (in a static electric field) is defined as the work needed per unit of charge to move a test charge between the two points. In the International System of Units, the derived unit for voltage (potential difference) is named volt.
