Introduction to Electromotive Force Voltage has many sources, a few of which are shown in Figure (PageIndex{2}). All such devices create a potential difference and can supply current if connected to a circuit. A special type of potential difference is known as electromotive force (emf)..
6.1: Electromotive Force
For a given emf and internal resistance, the terminal voltage decreases as the current increases due to the potential drop Ir of the internal resistance. Figure (PageIndex{6}): Schematic of a voltage source and its load resistor R.Since the internal resistance r is in series with the load, it can significantly affect the terminal voltage and the current …

10.1 Electromotive Force
If the electromotive force is not a force at all, then what is the emf and what is a source of emf? To answer these questions, consider a simple circuit of a 12-V lamp attached to a 12-V battery, as shown in Figure 10.3.The battery can be modeled as a two-terminal device that keeps one terminal at a higher electric potential than the second terminal.

Difference Between EMF and MMF
In short, a force which is responsible to drive flux in the magnetic circuit (same as electromotive (EMF) which drives electron in an electric circuit) is known as magnetomotive force . The SI unit of MMF is AT (Ampere-Turns) and G (Gilbert) is the CGS unit of magnetomotive force.
Electromotive Force (EMF)
Solar Power Generation: Photovoltaic cells within solar panels directly convert sunlight into electrical energy by generating EMF within the cells. Electronic Devices: Battery-Powered Devices: EMF produced through chemical reactions in batteries serves as the energy source for a myriad of portable devices, including smartphones, laptops, and electric vehicles.
