Electromotive Force

Postby Jarrett Peyrefitte 2K » Mon Feb 24, 2020 10:47 am

What is electromotive force? Why does it represent the maximum potential difference?

the electromotive force is Ecell, the max potential when very little current is flowing. When there is no current flowing, that is when the difference is at its maximum.

I thought electromotive force was the max potential of the cell before any current flow? How do you determine "little current is flowing"? Wouldn't that contradict the idea of max potential
