Chapter 11: Electromotive Force

All real sources of electromotive force have some internal resistance (r), which is due to the resistance of the materials and components within the device. The terminal voltage (V) of a source, such as a battery or a generator, is the potential difference across its terminals when connected to a load (external resistance, R). The relationship between EMF, internal

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.

Electromotive force is directly related to the source of potential difference, such as the particular combination of chemicals in a battery. However, emf differs from the voltage output of the device when current flows. The voltage across the terminals of a battery, for example, is less than the emf when the battery supplies current, and it declines further as the battery is depleted or

Electromotive Force is the electric potential generated by the battery or any electric source which allows the Negative Electromotive Force.

Electromotive Force

Electromotive force (emf) is a measure of the energy provided by a source, such as a battery or generator, per unit electric charge. It represents the work done on charges in an electric circuit and is responsible for driving current through that circuit. Understanding emf is crucial for analyzing how electric circuits function and how energy is transferred within them.

The electromotive force of a battery or other electric power source is the value of the potential difference it maintains between its terminals in the absence of current. In a typical car battery, the chemical reaction maintains the potential difference at a maximum of 12 volts between the positive and negative terminals, so the emf is 12 V. In
