SI unit (abbreviation amp, symbol A) of
electrical current. Electrical current is
measured in a similar way to water current,
in terms of an amount per unit time; one
ampere represents a flow of about 6.28 x
10^18 electrons per second, or a rate of flow
of charge of one coulomb per second. The
ampere is defined as the current that
produces a specific magnetic force between
two long, straight, parallel conductors
placed one metre apart in a vacuum. It is
named after the French scientist Andre
Ampere.
