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.
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.
Many scientists have been recognized with the assignment of their names as international units by the International Committee for Weights and Measures or as non-SI units. . The International System of Units (abbreviated SI from French: Système international d'unités) is the most widely used system of units of measureme

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 ...
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]
