[PAR] [TLE] Georg Ohm [SEP] Georg Simon Ohm (] ; 16 March 1789 – 6 July 1854) was a German physicist and mathematician.  As a school teacher, Ohm began his research with the new electrochemical cell, invented by Italian scientist Alessandro Volta.  Using equipment of his own creation, Ohm found that there is a direct proportionality between the potential difference (voltage) applied across a conductor and the resultant electric current.  This relationship is known as Ohm's law.
