am⋅pere

  [am-peer, am-peer]
Use Ampere in a Sentence
–noun Electricity.
the base SI unit of electrical current, equivalent to one coulomb per second, formally defined to be the constant current which if maintained in two straight parallel conductors of infinite length, of negligible circular cross section, and placed one meter apart in vacuum, would produce between these conductors a force equal to 2 × 10−7 newton per meter of length. Abbreviation: A, amp.
Also, ampère.

Origin:
1881; named after A. M. Ampère

am·pere   (ām'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.]
Am·père   (ām'pîr, äɴ-pěr')   
French physicist and mathematician who formulated Ampère's law, a mathematical description of the magnetic field produced by a current-carrying conductor.

Word Origin & History

ampere 
1881, "the current that one volt can send through one ohm," from Fr. ampère, from André M. Ampère (1775-1836), Fr. physicist. Shortened form amp is attested from 1886.

Main Entry: am·pere
Pronunciation: 'am-"pi(&)r also -"pe(&)r
Function: noun
1 : the practical mks unit of electric current thatis equivalent to a flow of one coulomb per second or to the steady current produced by one volt applied across a resistance of one ohm
2 : the base unit of electric current in theInternational System of Units that is equal to a constant current which when maintained in two straight parallel conductors of infinite length and negligible circular sections one meter apart in avacuum produces between the conductors a force equal to 2 × 10−7newton per meter of length
Amápère /än-per/,André Marie (1775–1836), French physicist. Ampère is credited with founding, naming, and developing the science of electrodynamics. He was the formulator of two lawsin electromagnetism relating magnetic fields to electric currents. The first person to develop techniques for measuring electricity, he invented an instrument that was a forerunner of the galvanometer.In 1881 at the suggestion of Sir Charles Bright, an international congress on electricity adopted ampere as a term for the standard unit of electric current.

Science Dictionary
ampere   (ām'pîr')  Pronunciation Key 
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.
Ampère   (ām'pîr', äm-pěr')  Pronunciation Key 
French mathematician and physicist who is best known for his analysis of the relationship between magnetic force and electric current. He formulated Ampère's law, which describes the strength of the magnetic field produced by the flow of energy through a conductor. The ampere unit of electric current is named for him.

ampere

unit of electric current in the Systeme International d'Unites (SI), used by both scientists and technologists. Since 1948 the ampere has been defined as the constant current which, if maintained in two straight parallel conductors of infinite length of negligible circular cross section and placed one metre apart in a vacuum, would produce between these conductors a force equal to 2 10-7 newton per metre of length. Named for the 19th-century French physicist Andre-Marie Ampere, it represents a flow of one coulomb of electricity per second. A flow of one ampere is produced in a resistance of one ohm by a potential difference of one volt. See electric current.
