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]:
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}.
