What is Georg Simon Ohm?
[[File:Georg Simon Ohm3.jpg|thumb]] '''Georg Simon Ohm''' (16 March 1789 - 6 July 1854) was a [[German people|German]] [[physicist]] and [[mathematician]]. During part of the time in his life, Ohm worked as a school teacher. Some of his [[research]] focused on the new [[electrochemical cell]], invented by Italian scientist [[Alessandro Volta]]. Using equipment he had created himself, 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]]. In 1881, after his death, the [[SI]] unit for [[electrical resistance]] was named ''Ohm'' in his honour. The uppercase [[Greek alphabet|Greek letter]] Omega (Ω) is used for the unit. {{authority control}} {{DEFAULTSORT:Ohm, Georg Simon}} [[Category:1789 births]] [[Category:1854 deaths]] [[Category:German physicists]]
