am·pere

 (ăm′pîr′)
n. Abbr. A
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. See Table at measurement.

Ampère

(ˈæmpɛə; French ɑ̃pɛr)
n
(Biography) André Marie (ɑ̃dre mari). 1775–1836, French physicist and mathematician, who made major discoveries in the fields of magnetism and electricity

ampere

(ˈæmpɛə)
n
1. (Units) the basic SI unit of electric current; the constant current that, when maintained in two parallel conductors of infinite length and negligible cross section placed 1 metre apart in free space, produces a force of 2 × 10–7 newton per metre between them. 1 ampere is equivalent to 1 coulomb per second
2. (Units) a former unit of electric current (international ampere); the current that, when passed through a solution of silver nitrate, deposits silver at the rate of 0.001118 gram per second. 1 international ampere equals 0.999835 ampere
Abbreviation: amp Symbol: A
[C19: named after André Marie Ampère]

am·pere

(ăm′pîr′)
A unit used to measure electric current. Electric current is measured by how great a charge passes a given point in a second. One ampere is equal to a flow of one coulomb per second.
