Author: Ohm, G[eorg] S[imon]
Title: The Galvanic Circuit Investigated Mathematically - In Taylor's Scientific Memoirs, Volume II, 1841
Place Published: London
Publisher:Richard and John E. Taylor
Date Published: 1841

vi, [8], 603, [1] pp. Illustrated with 26 plates, maps, etc. at rear of volume. (8vo) half leather and marbled boards, raised bands on spine, gilt lettering on spine, gilt top edge, marbled endpapers. First Edition.

Ohm's piece appears on pages 401-506, being the First English Edition of one of the most important works on electricity ever published, representing the discovery of "Ohm's Law", the fundamental law of electrical circuits, namely that E (electromotive force) equals I (current) x R (resistance). By working with wires of different thickness and lengths he Ohm found the quantity of current transmitted was inversely proportional to the length and directly proportional to the cross-sectional area of the wire. He was in this way able to define the resistance of the wire and in 1827 to show that there was a simple relation between the resistance, the electrical potential, and the amount of current carried. This came to be called Ohm's law.


Wear and soiling to leather and boards, rubbing to extremities, small chip at head of spine; library bookplate on front pastedown page dated August 1890, library stamp on verso of title page, occasional light foxing, some fraying to edges of some plates; very good.
