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.
Both Electrical and Magnetic Forces take place between two charged objects. These two forces are different aspects of one single electromagnetic interaction. The difference is that electrical forces occur between two objects, and magnetic forces occur between two objects in motion. Gravitational force is a relationship between two objects, their masses, and the distance between them.
