The Mathematics of Poker. Poker is a mathematical game, and itâs a game of incomplete information. That may sound complicated, but it really isn't. On a very basic level, winning poker starts with the selection of which starting hands to play.
Potential difference is the result. Potential difference is always less than electromotive force. Potential difference takes place between any two points in the circuit. Potential difference of two points depends on the resistance of those points. It does not remain constant.
For electricity to flow, there has to be something to push the electrons along. This is called an electromotive force (EMF) . A battery or power outlet creates the electromotive force that makes a current of electrons flow. An electromotive force is better known as a voltage.
