English → English (gcide) Definition: Ohm Ohm \Ohm\ ([=o]m), 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. [1913 Webster] 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. [1913 Webster]
