 [No title]   (Site not responding. Last check: 2007-10-22) Georg Simon Ohm, (March 16, 1787 - July 6, 1854), German physicist, was born in Erlangen and educated at the university there. He became professor of mathematics in the Jesuits' college at Cologne in 1817 and in the polytechnic school of Nuremberg in 1833, and in 1852 became professor of experimental physics in the university of Munich, where he later died. Ohm's name has been incorporated in the terminology of electrical science in Ohm's Law, the proportionality of current and voltage in a resistor, and adopted as the SI unit of resistance, the ohm (symbol Ω). wikiwhat.com /encyclopedia/g/ge/georg_ohm.html   (160 words)

 Ohm - Wikipedia, the free encyclopedia The ohm (symbol: Ω) is the SI unit of electrical impedance or, in the direct current case, electrical resistance, named after Georg Ohm. An ohm is a resistance that produces a potential difference of one volt when a current of one ampere is flowing through it. A measurement in ohms is the reciprocal of a measurement in siemens, the SI unit of electrical conductance. en.wikipedia.org /wiki/Ohm   (712 words)

 Ohm   (Site not responding. Last check: 2007-10-22) Had Ohm's brothers and sisters all survived he would have been one of a large family but, as was common in those times, several of the children died in their childhood. Ohm's father, angry that his son was wasting the educational opportunity that he himself had never been fortunate enough to experience, demanded that Ohm leave the university after three semesters. Ohm had believed that his publications would lead to his receiving an offer of a university post before having to return to Cologne but by the time he was due to begin teaching again in September 1827 he was still without such an offer. www.geocities.com /bioelectrochemistry/ohm.htm   (4218 words)

 BookRags: Georg Simon Ohm Biography Ohm, who was born on March 16, 1789 in Erlangen, Bavaria, was the son of a self-educated locksmith. In 1827 Ohm issued his "law," stating that the amount of current passing through a wire was inversely proportional to the length and directly proportional to the thickness of a wire. Ohm went a step beyond, stating the relationship in mathematical terms: V = IR (the voltage of the current is equal to the current in the circuit times the resistance); doubling the voltage doubles the current, and doubling resistance halves the current. www.bookrags.com /biography/georg-simon-ohm-wop   (638 words)

 The Life of Georg Ohm   (Site not responding. Last check: 2007-10-22) Although Georg Ohm discovered one of the most fundamental laws of current electricity, his work was virtually ignored and he lived in poverty for much of his life. Ohm became a professor of mathematics at the Jesuit College of Cologne in 1817. Ohm attempted to produce a mathematical description of electrical conduction based on ideas contained in Fourier's study of heat conduction. www.fis.unb.br /Fis3Exp/wwwtdec.coe.drexel.edu/edl_website/Docs/INSTR_LABS/EDL_LAB2/Georg_Ohm/Ohm.html   (250 words)

 The Inventors (E) Georg Simon Ohm's father was a rather remarkable man who had educated himself to a high level and was able to give his sons an excellent education through his own teachings and brought them to a high standard in mathematics, physics, chemistry and philosophy. Ohm's firsts paper published in 1825 examines the decrease in the electromagnetic force produced by a wire as the length of the wire increased. Ohm believed that the communication of electricity occurred between "contiguous particles" which is the term Ohm himself uses. www.theelevatormuseum.org /e/e-11.htm   (494 words)

 Radio-Electronics.Com :: Georg Simon Ohm   (Site not responding. Last check: 2007-10-22) Georg Simon Ohm was born on 18th March 1789 in Erlangen in Bavaria. Georg entered school at the age of 11 and he proved to be a bright student, and in 1805 he moved on to University at Erlangen. Whilst doing this Ohm noticed that the type of conductor had an effect on the flux and as a result he performed experiments to find out if there might be any relationship between the voltage, current and the material of the wire. www.radio-electronics.com /info/radio_history/gtnames/ohm.php   (680 words)

 George Ohm Georg Simon Ohm was a German physicist born in Erlangen, Bavaria, on March 16, 1787. Ohm was forced to resign from his high-school teaching position and he lived in poverty and shame until he accepted a position at Nüremberg in 1833 and although this gave him the title of professor, it was still not the university post for which he had strived all his life. Ohm had discovered the distribution of electromotive force in an electrical circuit, and had established a definite relationship connecting resistance, electromotive force and current strength. www.corrosion-doctors.org /Biographies/OhmBio.htm   (703 words)

 Georg Simon Ohm: The Discovery of Ohm's Law Georg Ohm, German mathematician and physicist, began his important publications in 1825. Ohm's law, named after its discoverer, states that the potential difference V between the ends of a conductor or resistor R and the current I flowing through R are proportional at a given temperature: Ohm's law is never completely accurate, if R is assumed to be constant, for "real world" devices, because no real device is an ohmic device for every voltage and current - at some level, the device will open or short, for example, by burning up or arcing. www.juliantrubin.com /bigten/ohmlawexperiments.html   (825 words)

 Ohm Ohm’s main interest was current electricity, which had recently been advanced by Alessandro Volta’s invention of the battery. Ohm’s law stated that the amount of steady current through a material is directly proportional to the voltage across the material, for some fixed temperature. Ohm’s law of 1826 states that if the given temperature remains constant, the current flowing through certain conductors is proportional to the potential difference (voltage) across it. projects.sd3.k12.nf.ca /scibios/ohm.htm   (572 words)

 Famous Mathematicians Georg Simon Ohm was born to Johann Wolfgang Ohm and Maria Elizabeth Beck in 1787 in Erlangen. Ohm entered the University of Erlangen but lost funding for it by his father after three semesters because Georg was too interested in student life.

 Resistor Color Code, Tutorial, Formulas, Georg Simon Ohm history, What is "Rho". Georg Simon Ohm was born on March 16, 1789 in the city of Erlangen in Bavaria, which is now Germany. Ohm was sent to Switzerland where, in September 1806, took up a post as a mathematics teacher in a school in Gottstadt bei Nydau. Ohm's Law is not a fundamental law like Newton's Laws or the laws of thermodynamics, but an empirical description of a property shared by many electrical materials. www.uoguelph.ca /~antoon/gadgets/resistors/resistor.htm   (2235 words)

 Ohm biography Langsdorf, however, advised Ohm to continue with his studies of mathematics on his own, advising Ohm to read the works of Euler, Laplace and Lacroix. This was a better school than any that Ohm had taught in previously and it had a well equipped physics laboratory. In two important papers in 1826, Ohm gave a mathematical description of conduction in circuits modelled on Fourier's study of heat conduction. www-groups.dcs.st-and.ac.uk /~history/Biographies/Ohm.html   (1954 words)

 Ohm Ohm utilized as an analogy to conductivity, the mathematical physics governing the flow of liquids and the thermodynamic equations of Fourier governing the dissipation of heat within a body. His results, now known as Ohm¹s law, were initially dismissed, and full recognition of his work did not come until 1841 when he was awarded the Copley Medal of the Royal Society and, belatedly, in 1881 when the International Electrical Congress established the ohm as the basic unit of resistance. As a preliminary to the formulation of his fundamental laws, Ohm defined the electroscopic force operationally as that force the presence of which was detected by means of an electroscope, and the quantity of electricity of a body as the product of the magnitude of its electroscopic times its volume. www.sparkmuseum.com /BOOK_OHM.HTM   (236 words)
