Die galvanische Kette, mathematisch bearbeitet
One folding engraved plate. iv, 245, [1] pp. 8vo, cont. half-cloth & marbled boards (ends of spine almost invisibly repaired), spine gilt. Berlin: T.H. Riemann, 1827. First edition 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. "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 current. 'Ohm's law' - that the resistance of a given conductor is a constant independent of the voltage applied or the current flowing - was arrived at theoretically by analogy with Fourier's heat measurements (1800-14)."-Printing & the Mind of Man 289. It is known that the publisher was forced to pulp most of the copies of this book due to lack of sales. A very fine and fresh copy with the bookplate of Alfred Schmid. ?
