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]
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.
1861: Grade school teacher Philipp Reis presents his telephone in Frankfurt, inventing the loudspeaker as a by-product. 1867: French poet and philosopher Charles Cros (1842–1888) presents the construction principle of a phonograph in his 'paréophone', which turned out not to be a commercial success at the time.
One of the functions of many types of multimeters is the measurement of resistance in ohms.. The ohm is defined as an electrical resistance between two points of a conductor when a constant potential difference of one volt (V), applied to these points, produces in the conductor a current of one ampere (A), the conductor not being the seat of any electromotive force.
The Technische Hochschule Nürnberg Georg Simon Ohm (shortened TH Nürnberg; English name Nuremberg Institute of Technology Georg Simon Ohm) is a public Technische Hochschule in Nuremberg, Bavaria. With its 12,200 students and 1,800 faculty members, it is the second biggest Technische Hochschule in Bavaria. President is Niels Oberbeck.
