Amperes

am·pere   (ām'pîr')    n.   Abbr. A A unit of electric current in the meter-kilogram-second system. It is the steady current that when flowing in straight parallel wires of infinite length and negligible cross section, separated by a distance of one meter in free space, produces a force between the wires of 2 × 10-7 newtons per meter of length. A unit in the International System specified as one International coulomb per second and equal to 0.999835 ampere. See Table at measurement. [After André Marie Ampère.]

ampere 

Main Entry: am·pere
Pronunciation: 'am-"pi(&)r also -"pe(&)r
Function: noun
1 : the practical mks unit of electric current thatis equivalent to a flow of one coulomb per second or to the steady current produced by one volt applied across a resistance of one ohm
2 : the base unit of electric current in theInternational System of Units that is equal to a constant current which when maintained in two straight parallel conductors of infinite length and negligible circular sections one meter apart in avacuum produces between the conductors a force equal to 2 × 10⁻⁷newton per meter of length
Amápère /äⁿ-per/,André Marie (1775–1836), French physicist. Ampère is credited with founding, naming, and developing the science of electrodynamics. He was the formulator of two lawsin electromagnetism relating magnetic fields to electric currents. The first person to develop techniques for measuring electricity, he invented an instrument that was a forerunner of the galvanometer.In 1881 at the suggestion of Sir Charles Bright, an international congress on electricity adopted ampere as a term for the standard unit of electric current.
