Georg Simon Ohm (March 16, 1789 - July 6, 1854) was a German physicist who put forward many theories in the field of electricality. His best known work is the theory of the relationship between electrical current, voltage, and conductor resistance within the circuit, commonly called Ohm's Law.

Georg Ohm was born to a pair of Johann Wolfgang Ohm, a locksmith, and Maria Elizabeth Beck, a tailor. Although his father only works as a locksmith, he is able to provide his children with a high education through his own teachings. Actually Georg Ohm was born as 7 brothers, but only 3 survived through his childhood, namely Georg, Martin (famous mathematician), and Elizabeth Barbara. In 1805 Ohm entered the University of Erlangen but left in the third semester and then went to teach mathematics at Gottstadt bei Nydaud, Switzerland. Georg Ohm left the school in March 1809 to become a private tutor at NeuchÃ¢tel. On the advice of Karl Christian von Langsdorf, he resumed his studies in mathematics and in April 1811 he returned to the University of Erlangen.

On October 25, 1811, Ohm obtained a doctorate in mathematics from Erlangen and joined as a staff of mathematics lecturers. Realizing that the job had no good prospects and little money, he left the job and accepted the Bavarian government's offer. The offer to teach as a mathematics and physics teacher at a low-quality school in Bamberg received in January 1813. He also worked as a primary school textbook on geometry, but Ohm did not feel happy with his work. In February 1816, the school was closed and the Bavarian government sent him to a crowded school in Bamberg to teach mathematics. On September 11, 1817, Georg Ohm accepted an offer of teaching mathematics and physics at the Jesuit Gymnasium, Cologne. There he began experimenting until his move to Berlin in March 1928 because the enthusiasm for his work was not very good.

In 1833, Ohm got a job and a professorship from one of the universities at NÃ¼remberg. Nevertheless, the university was not what he aspired to be. The public recognition and appreciation of Ohm's great works was too late for him to get it, he had to work hard and for a long time. This is probably due to his lack of good relationships with several powerful figures, such as Johannes Schultz, an influential figure in the education department of Berlin, and Georg Friedrich Pohl, professor of physics in the city. The Royal Society awarded the Copley Medal to Ohm in 1841 and a year later, he became a member of the Royal Society. The Berlin and Turin Academies also chose Ohm as a member, and in 1845, he became a full member of the Bavarian Academy. In 1849, Ohm took up a position in Munich as curator of the Bavarian Academy and began teaching at the University of Munich. Two years before his death, he achieved his ambition to become chair of the field of physics studies at the University of Munich.

The first scientific manuscript published by Ohm contains the examination of the electromagnetic force decrease generated by an extended length of wire. The text shows a purely mathematical relationship based on his experiments. A year later, in 1826, Ohm published two scientific texts that illustrate the conduction of a circuit model based on Fourier's study of heat conduction. In it, he also proposed a theory to explain the galvanic elektrisitas. The second manuscript he wrote that year included the first step of a comprehensive theory that served to support the publication of his famous book containing Ohm's law (1827).

When the new electrochemical cell was discovered by Alessandro Volta, Omh used it for his experiment to produce Ohm's law. With the help of self-made equipment, Ohm argues that the electric current flowing through the wire is proportional to the cross-sectional area and inversely proportional to the length of the wire. Ohm's law was written in a book called Die galvanische Kette, mathematisch bearbeitet (1827).
