The basic unit of electric current. One ampere is equivalent to a flow of 1 coulomb per second. Abbreviation: a, A, amp.
1. A former unit of electric current (slightly smaller than the SI ampere); SYN. international ampere.
2. The basic unit of electric current adopted under the System International d'Unites; SYN. amp, A.
A unit used to define the rate of flow of electricity (current) in a circuit; units are one coulomb (6.25 x 108 electronics) per second.
unit for measuring amount of electrical current.
unit of intensity of electric current (current produced by one volt acting through resistance of one ohm) (abbr. amp.). ampere hour, unit of quantity of electric current (quantity flowing in one hour at one amp).
SI unit (abbreviation amp, symbol A) of electrical current. Electrical current is measured in a similar way to water current, in terms of an amount per unit time; one ampere represents a flow of about 6.28 × 1018 electrons per second, or a rate of flow of charge of one coulomb per second.
The ampere is defined as the current that produces a specific magnetic force between two long, straight, parallel conductors placed one meter (3.3 ft) apart in a vacuum. It is named for the French scientist André Ampčre.
Jedinica za merenje jačine električne struje, nazvana po slavnom franc. matematičaru i fizičaru A. Amperu (1775-1836): kulon za sekudnu ili struja koja prolaskom kroz vodeni rastvor nitrata srebra za sekundu izdvoji 0,001118 grama srebra.
