Berlin: J.G.F. Kniestädt for T.H. Riemann, 1827. First edition. PMM 289 - Measuring Electricity. First edition of "Ohm's great work" (DSB), containing the fully-developed presentation of his theory of electricity, including Ohm's Law. "Ohm's great contribution − 'The Galvanic Chain Mathematically Calculated' − was to measure the rate of current flow and the effects of resistance on the current. 'Ohm's law' − that the resistance of a given conductor is a constant independent of the voltage applied or the current flowing (that is, C = E/R, where C = current, E = electromotive force and R = resistance) − was arrived at theoretically by analogy with Fourier's heat measurements (1800-14)" (PMM). "The expression "investigated mathematically" in the title of Ohm's book described his objective: to deduce the properties of the galvanic circuit from a set of "fundamental laws." The first of these laws states that electricity passes only between adjacent particles of the conductor and that the… Ler mais

One folding engraved plate. iv, 245 pp. (lacking the errata leaf & leaf of ads). 8vo, cont. grey paste-paper boards (lower joint with short split at head & foot). Berlin: T.H. Riemann, 1827. First edition, and a splendid association copy, of this pioneering work which contains one of the most important discoveries in electrical science - "Ohm's law" - the basis of the present system of electrical measurement. Ohm discovered the unit of resistance in an electrical current. This copy belonged to the "Prince of Mathematicians" - Carl Friedrich Gauss - and has the "Gauss-Bibliothek" stamp on the title. It is quite exciting to be able to link two of the greatest 19th-century scientists through an important book like this. "In the field of electrical measurement Ohm was the great pioneer...Ohm's great contribution - 'The Galvanic Chain Mathematically Calculated' - was to measure the rate of current flow and the effects of resistance on the… Ler mais
