Key Concepts

Electromotive Force (EMF)

EMF is a concept in electrical engineering and physics that quantifies the energy provided per unit charge by a source, such as a battery or generator. Despite the term 'force,' it does not represent a force in the classical sense (i.e., it does not cause acceleration of a charge) but rather a potential difference that drives current in a circuit.

Potential Difference (Voltage)

Voltage, or potential difference, is the measure of energy per unit charge between two points in a circuit, and it is measured in volts. The term 'electromotive force' is considered inaccurate because it implies a force acting on charges, while in reality, it refers to this energy conversion characteristic, not an actual force as defined by Newtonian mechanics.
