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.
Electromotive force. Electromotive force, also called emf (denoted E {\displaystyle {\mathcal {E}}} and measured in volts), is the voltage developed by any source of electrical energy such as a battery or dynamo. It is generally defined as the electrical potential for a source in a circuit.
