{ ||Am`père" (äN`pâr"), Am*pere" (ăm*pār"), } n. [From the name of a French electrician.] (Elec.) The unit of electric current; -- defined by the International Electrical Congress in 1893 and by U. S. Statute as, one tenth of the unit of current of the C. G. S. system of electro-magnetic units, or the practical equivalent of the unvarying current which, when passed through a standard solution of nitrate of silver in water, deposits silver at the rate of 0.001118 grams per second. Called also the international ampère.

• a unit of electrical current, the standard base unit in the International System of Units. Abbreviation: amp, Symbol: A
        Definition: The ampere is that constant current which, if maintained in two straight parallel conductors of infinite length, of negligible circular cross-section, and placed 1 metre apart in vacuum, would produce between these conductors a force equal to 2 x 10–7 newton per metre of length.
