The electric potential difference is the difference in electric potential represented by V which shortens the word volt, the unit of measurement of the difference in electromotive force (EMF) or ...

The simplest complete circuit is a piece of wire from one end of a battery to the other. An electric current can flow in the wire from one end of the battery to the other, but nothing useful happens.
