am·pere ( m pîr )n. Abbr. A 1. 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. 2. A unit in the International System specified as one International coulomb per second and equal to 0.999835 ampere. See Table at measurement. [After André Marie Ampère.] |
ampere [ˈæmpɛə]
n
1. (Mathematics & Measurements / 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. (Mathematics & Measurements / 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
[named after André Marie Ampère (1775-1836), French physicist and mathematician]
| ampere (mpîr) The SI unit used to measure electric current. Electric current through any given cross-section (such as a cross-section of a wire) may be measured as the amount of electrical charge moving through that cross-section in one second. One ampere is equal to a flow of one coulomb per second, or a flow of 6.28 × 1018 electrons per second. |
