  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]

From WordNet (r) 2.0 [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

From The Free On-line Dictionary of Computing (27 SEP 03) [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}.
