- Electromotive force is defined as the electric pressure that makes a current flow in a circuit.
An example of electromotive force is voltage generated by a battery.
the force or electric pressure that causes or tends to cause a current to flow in a circuit, equivalent to the potential difference between the terminals and commonly measured in volts: abbrev. E, EMF, or emf
The energy per unit charge that is converted reversibly from chemical, mechanical, or other forms of energy into electrical energy in a battery or dynamo.
