History of electromagnetic theory used to create positively charged anodes and negatively charged cathodes. When a conductor was attached between these, the difference in the electrical potential (also known as voltage) drove a current between them through the conductor. The potential difference between two points is measured in units of volts in recognition of Volta's work. The first mention of voltaic electricity, although not recognized as such at the time, was probably made by Johann Georg Sulzer in 1767, who, upon placing a small disc of zinc under his tongue and a small disc of copper over it, observed a peculiar taste when the
Jörg Ohm – those players were thought to have less potential than their comrades who joined SC Leipzig. However, at the end of the 1963–64 season, BSG Chemie Leipzig won the championship, with Ohm appearing in four matches. He stayed with Chemie Leipzig until 1968 and appeared in 33 matches for the side. However, when they won the FDGB-Pokal in 1966, Ohm was missing from the final squad. At the beginning of the 1968–69 season, Ohm joined 1. FC Magdeburg and won the cup for the first time in 1969. Not only did he play in the final this time, but also
