Ohm's feeling were hurt, he decided to remain in Berlin and, in March 1828, he formally resigned his position at Cologne. In fact it was in Britain that the unit of resistance was first named after Ohm. Then in 1881 the unit was adopted by international agreement and Ohm's name was made immortal.

Finally he had achieved the recognition he wanted during his life time.

In the case where the circuit is broken, the resistance is infinite, and the current drops to zero, as the above formula demonstrates.

In 1841, the Royal Society of London honored him with the Copley Medal for his extraordinary efforts. Today there are statues of him, one notable one is at the Technical University of Munich in Bavaria, Germany.

    Ohm's Law

    An electric battery will produce a fixed amount of electromotive force, or voltage, in a circuit. This work appeared in its most complete form in 1927 as a book entitled "The Galvanic Circuit Mathematically Treated." In it, he applied, by analogy, the same treatment to the flow of electricity as Joseph Fourier had in his groundbreaking study of heat flow.

    Biography

    Georg Simon Ohm came from a Protestant family. in neither the introduction nor the body of the work, which contained the more rigorous development of the theory, did Ohm bring decisively home either the underlying unity of the whole or the connections between fundamental assumptions and major deductions.

    Georg Simon entered Erlangen Gymnasium at the age of eleven but there he received little in the way of scientific training. This relationship, known as Ohm's law, represents the true beginning of electrical circuit analysis. The result was not contained in Ohm's firsts paper published in 1825, however, for this paper examines the decrease in the electromagnetic force produced by a wire as the length of the wire increased.

    Then in April 1811 he returned to the University of Erlangen. He performed many experiments to try to determine any relationships that might exist. For example, although his theory was conceived as a strict deductive system based on three fundamental laws, he nowhere indicated precisely which of their several mathematical and verbal expressions he wished to be taken as the canonical form. It is interesting that Ohm's presents his theory as one of contiguous action, a theory which opposed the concept of action at a distance.

    The Bavarian government then sent him to an overcrowded school in Bamberg to help out with the mathematics teaching.
