Talk:Electromotive force

Emf is often used as a synonym for potential difference, where the potential difference is induced by an energy source such as a battery. This usage is considered obsolete.

I thought that it is not the same because of the internal resistance in the battery, and that therefore the concept of emf is still needed for a battery. - Patrick 12:09 Feb 4, 2003 (UTC)
