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.
If the charges are in motion, howeverâand in this instance motion or rest is understood in relation to the observerâthen it appears as though a different sort of force, known as magnetism, exists between them. In fact, the difference between magnetism and electricity is purely artificial. Both are manifestations of a single fundamental force, with magnetism simply being an abstraction that people use for the changes in electromagnetic force created by the motion of electric charges.
