A fraction of an ampere through the human heart muscles can be fatal.
The filament current of an audion-bulb averages about one ampere.
An ampere is 6.3 billion electrons passing one point in a circuit, in one second.
But it is a little different when one is interested in an ampere.
A mil-ampere is a thousandth of an ampere just as a millimeter is a thousandth of a meter.
Now I want to tell you how the physicists at the Bureau know what is an ampere.
The ammeter indicated only half as much as before, that is .008 ampere.
But I admired him, for he had every ampere of his self-possession in hand; my own case was different.
The increase in weight shows the amount of chemical action which is proportional to the ampere hours.
Its resistance is just such that 110 volts of pressure send one ampere through it.
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.
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.
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.
