Electromotive Force (EMF): Definition, Example, & Equation
Electromotive force, or emf, is the energy required to move a unit electric charge by an energy source such as a battery, cell, or generator. It is defined as the potential difference across the terminals where there is no current passing through it, i.e., an open circuit with one end positive and the other end negative.

In electromagnetism and electronics, electromotive force is an energy transfer to an electric circuit per unit of electric charge, measured in volts. Devices called electrical transducers provide an emf by converting other forms of energy into electrical energy. Other electrical equipment also produce an emf, such as batteries, which convert chemical …
If the electromotive force is not a force at all, then what is the emf and what is a source of emf?
