Georg Simon Ohm (/ oʊ m /; [1] German: [ˈɡeːɔʁk ˈʔoːm]; [2] [3] 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.
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. Ohm explained his experimental results by a slightly more complex equation than the modern form above (see § History below).
Notable developments early in this century include the work of Georg Ohm, who in 1827 quantified the relationship between the electric current and potential difference in a conductor, Michael Faraday, the discoverer of electromagnetic induction in 1831. [26] In the 1830s, Georg Ohm also constructed an early electrostatic machine.

Michael Faraday invented the electric motor in 1821, and Georg Ohm mathematically analysed the electrical circuit in 1827. [22] Electricity and magnetism (and light) were definitively linked by James Clerk Maxwell, in particular in his "On Physical Lines of Force" in 1861 and 1862. [23]: 148
1826 – Georg Simon Ohm states his Ohm's law of electrical resistance in the journals of Schweigger and Poggendorff, and also published in his landmark pamphlet Die galvanische Kette mathematisch bearbeitet in 1827. The unit ohm (Ω) of electrical resistance has been named in his honor. [18]
