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.
The difference between the electric potential at two points, A and B, is measured in volts and called the Potential Difference. However if you connected a resistor between points A and B, no current would flow. Now consider you battery, with the same voltage across its terminals as the PD between A and B above.
An electric force is exerted between any two charged objects. Objects with the same charge (both positive or both negative) will repel each other, and objects with opposite charges (one positive and one negative) will attract each other.
