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.
It may be pointed out that the word electromotive force is a misnomer. It does not represent force on the carriers of electricity. Instead, it represents the potential difference between the two poles in an open circuit (when no current is drawn from the cell).
