Large projection-apparatus for electric lamp of 30 ampère with triple collecting lens of 210 mm aperture.
This stimulated others, and ampère applied it to the galvanometer the same year.
The discoveries of ampère as to the laws of electricity have been likened to the discovery of Newton of the law of gravitation.
No less an authority than the illustrious ampère declared her to be "a genius in geometry."
Now connect our standard cell—one volt—through one ohm resistance and we have a current of one ampère.
With the means at ampère's disposal, we may say that this was impossible.
ampère entitled his immortal work, 'Théorie des phénomènes électrodynamiques, uniquement fondée sur l'expérience.'
In spite of its apparent complexity, ampère's theory greatly extends our mathematical vision into the interior of the molecules.
We do honor to the name of ampère whenever we measure an electric current, for electric currents are measured in "amperes."
This would no longer be true, if one accepts the theory of ampère, if there were open currents.
1881, "the current that one volt can send through one ohm," from French ampère, named for French physicist André-Marie Ampère (1775-1836). Shortened form amp is attested from 1886.
ampere am·pere (ām'pēr')
A unit of electric current in the meter-kilogram-second system, equal to the current that, flowing in two parallel wires one meter apart, produces a force of 2 × 10-7 newtons per meter.
A unit in the International System specified as one International coulomb per second and equal to 0.999835 ampere.
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.
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.
