Georg Simon Ohm (/ oʊ m /; [1] German: [ˈɡeːɔʁk ˈʔoːm]; [2] [3] 16 March 1789 – 6 July 1854) was a German mathematician and physicist. As a school teacher, Ohm began his research with the new electrochemical cell , invented by Italian scientist Alessandro Volta .
Georg Simon Ohm. Futile attempts were made by Charles Babbage, Peter Barlow, John Herschel and others to explain this phenomenon. The true explanation was reserved for Faraday, namely, that electric currents are induced in the copper disc by the cutting of the magnetic lines of force of the needle, which currents in turn react on the needle.

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]
Ohm's law in Georg Ohm's lab book. Ohm's law was probably the most important of the early quantitative descriptions of the physics of electricity. We consider it almost obvious today. When Ohm first published his work, this was not the case; critics reacted to his treatment of the subject with hostility.
Ohm's law, in physics: the ratio of the potential difference (or voltage drop) between the ends of a conductor (and resistor) to the current flowing through it is a constant. Discovered by and named after Georg Simon Ohm (1789–1854). Ohm's acoustic law is an empirical approximation concerning the perception of musical tones, named for Georg ...

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.
