Electromotive force is measured in which unit?

Electromotive force (EMF) is a measure of the energy provided by a source of electrical energy per unit charge. It is defined as the potential difference that drives an electric current through a circuit when work is performed on the charges. The unit of EMF is the volt, which is equivalent to one joule per coulomb.

Understanding that EMF represents the energy supplied to charge carriers in an electric circuit clarifies why the volt is the appropriate unit. This aligns with the fundamental principles of electrical engineering and physics, where volts are used to quantify the energy available to push the electric current through a circuit.
