3 definitions found From Webster's Revised Unabridged Dictionary (1913) [web1913]: Ohm \Ohm\, n. [So called from the German electrician, G.S. Ohm.] (Elec.) The standard unit in the measure of electrical resistance, being the resistance of a circuit in which a potential difference of one volt produces a current of one amp['e]re. As defined by the International Electrical Congress in 1893, and by United States Statute, it is a resistance substantially equal to 10^{9} units of resistance of the C.G.S. system of electro-magnetic units, and is represented by the resistance offered to an unvarying electric current by a column of mercury at the temperature of melting ice 14.4521 grams in mass, of a constant cross-sectional area, and of the length of 106.3 centimeters. As thus defined it is called the {international ohm}. {Ohm's law} (Elec.), the statement of the fact that the strength or intensity of an electrical current is directly proportional to the electro-motive force, and inversely proportional to the resistance of the circuit. From WordNet r 1.6 [wn]: ohm n 1: a unit of electrical resistance equal to the resistance between two points on a conductor when a potential difference of one volt between them produces a current of one ampere 2: (1787-1854) the German physicist who formulated Ohm's Law [syn: {Ohm}, {Georg Simon Ohm}] From The Free On-line Dictionary of Computing (13 Mar 01) [foldoc]: OhmThe {MKS} unit of electrical resistance. One Ohm is the resistance of a conductor across which a {potential difference} of one {Volt} produces a {current} of one {Ampere}. [Who was Mr Ohm?] (1998-02-27)
