GNU Project's publication of CIDE, the Collaborative International Dictionary of English 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]
WordNet 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: German physicist who formulated Ohm's Law (1787-1854) [syn:
Georg Simon Ohm]
FOLDOC Ohm

The 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.
