Ampere Definition

ămpîr
amperes
noun
amperes
The basic unit of electric current, equal to one coulomb per second and equivalent to the current, flowing in two straight parallel wires of negligible cross section separated by a distance of one meter, that produces a force between the wires of 2.0 × 10−7 newtons per meter of length. The value of an ampere in the International System differs very slightly from that in the meter-kilogram-second-ampere system of units.
American Heritage
The basic unit of electric current intensity, equal, in the MKS system, to a rate of flow of charge in a conductor or conducting medium of one coulomb per second and, in the SI system, to a constant current that, if maintained in two straight parallel conductors of infinite length and negligible circular cross section placed one meter apart in a vacuum, would produce between these conductors a force equal to 2×10-7 newton per meter of length: abbrev. A or amp.
Webster's New World

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.
