In physical science, "emf" stands for "electromotive force." It refers to the energy provided by a power source (such as a battery or generator) per unit electric charge that passes through the source. EMF is a measure of the work done to move a charge through an electric circuit and is typically measured in volts (V).
EMF can be thought of as the voltage developed by any source of electrical energy when no current is flowing. It represents the potential difference that drives electric current in a circuit. In practice, the term "emf" is often used when discussing the concept of circuits, batteries, and electrical devices.
In summary, electromotive force is a fundamental concept in understanding how electrical systems operate.
