Omhs+law

In electrical circuits //**Ohm's law**// states that the current through a conductor between two points is directly proportional to potential difference or voltage across the two points, and inversely proportional to the resistance between them, provided that the temperature remains constant. The mathematical equation that describes this is:

Where //V// is the potential difference measured //across// the resistance in units of volts; //I// is the current through the resistance in units of amperesand //R// is the resistance of the conductor in units of |ohms.Specifically, Ohm's law states that the //R// in this relation is constant, independent of the current. The law was named after the German physicist Georg Ohm, who, in a treatise published in 1827, described measurements of applied voltage and current through simple electrical circuits containing various lengths of wire. He presented a slightly more complex equation than the one above - wikipedia
