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 .
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).
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.
The university got its name in honor of Georg Simon Ohm who was a professor and headmaster of the predecessor of the Hochschule, the Polytechnische Schule, between 1839 and 1849. The logo of the Technische Hochschule is the Ω as a reference to Ohm the SI derived unit for electric resistance named after Georg Simon Ohm.
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 (1827): Published by Georg Simon Ohm in 1827, Ohm's law established the relationship between voltage, current, and resistance, paving the way for more precise electrical measurements. Wheatstone Bridge (1833, 1843): The Wheatstone bridge , invented by Samuel Hunter Christie in 1833 and popularized/improved by Sir Charles Wheatstone in ...

In the 1830s, Georg Ohm also constructed an early electrostatic machine. The homopolar generator was developed first by Michael Faraday during his memorable experiments in 1831. It was the beginning of modern dynamos – that is, electrical generators which operate using a magnetic field.
