What is typically the unit of measurement for electromotive force?

The unit of measurement for electromotive force is volts. Electromotive force (EMF) refers to the electrical action produced by a non-mechanical source, and it represents the energy supplied per coulomb of charge that is moved through an electric circuit.

One volt is defined as the potential difference when one joule of energy is used to move one coulomb of charge. This relationship highlights the connection between energy, charge, and voltage, emphasizing that volts quantify how much energy is available to push charges through a circuit. Understanding this concept is fundamental in electrical engineering and physics, as it underpins the operation of batteries, generators, and other electrical devices.
