ampere
am·pere A0263300 (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.]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) n1. (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 second2. (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 ampereAbbreviation: amp Symbol: A [C19: named after André Marie Ampère]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. [1881; after A. M. Ampère] Am•père (ˈæm pɪər, æmˈpɪər, Fr. ɑ̃ˈpɛr)
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.

ampere (A) [am´pēr] the base SI unit of electric current strength, defined in terms of the force of attraction between two parallel conductors carrying current.Am·père (ahm'pēr), André-Marie, French physicist, 1775-1836. See: ampere, statampere, Ampère postulate.
am·pere (A), (am'pēr), 1. The practical unit of electrical current; the absolute, practical ampere originally was defined as having the value of one tenth of the electromagnetic unit. 2. Legal definition: the current that, flowing for 1 second, will deposit 1.118 mg of silver from silver nitrate solution. 3. Scientific (SI) definition: the current that, if maintained in two straight parallel conductors of infinite length and of negligible circular cross-sections and placed 1 m apart in a vacuum, produces between them a force of 2 × 10-7 N/m of length.
