Definitions

from The American Heritage® Dictionary of the English Language, 5th Edition.

  • noun The SI-derived unit of electrical resistance of a conductor through which a current of one ampere flows when subjected to a one-volt potential across its terminals.

from The Century Dictionary.

  • noun In electricity, the unit of resistance (see resistance).
  • noun An abbreviation of On His (or Her) Majesty's Service.

  • noun (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 ampére. As defined by the International Electrical Congress in 1893, and by United States Statute, it is a resistance substantially equal to 109 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.
  • noun (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.
