Study Notes

Electromotive Force (EMF)

Electromotive force is the energy per unit electric charge provided by an energy source.
Examples of energy sources that impart EMF include electric generators and batteries.
In these energy sources, energy is converted from one form to another.
This energy conversion occurs as the device performs work on the electric charge being transferred within itself.
