The definition of an ampere is the basic unit for measuring electricity.

(noun)

The accepted standard unit used for measuring how fast an electric current flows is an example of an ampere.

See ampere in Webster's New World College Dictionary

noun

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 newton per meter of length: abbrev. A or amp

Origin: after André Marie Ampère

See ampere in American Heritage Dictionary 4

noun 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.
