## 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.

[After André Marie Ampère.]

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

## am•pere

(ˈæm pɪər, æmˈpɪər)

n.
the SI unit of electrical current, equal to a constant current that would produce a force of 2 x 10−7 newton per meter of length when maintained in two straight parallel conductors of infinite length and negligible circular cross section and placed one meter apart in a vacuum. Abbr.: A, amp.

n.
André Marie, 1775–1836, French physicist.

## 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.

## ampere

1. The unit of electric current in the international system.
2. (A) The unit for measuring electric current.
