Voltage power and current, where 1 volt = 1 watt (of power) per 1 ampere (of current). This definition is equivalent to the more commonly used 'joules per coulomb'. Voltage or electric potential difference is denoted symbolically by , but more often simply as "V", for instance in the context of Ohm's or Kirchhoff's circuit laws. Electric potential differences between points can be caused by electric charge, by electric current through a magnetic field, by time-varying magnetic fields, or some combination of these three. A voltmeter can be used to measure the voltage (or potential difference) between two points in a
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
