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.
