The filament current of an audion-bulb averages about one ampere.
A 40-watt-incandescent lamp takes about 0.4 ampere of current.
But it is a little different when one is interested in an ampere.
Now I want to tell you how the physicists at the Bureau know what is an ampere.
A mil-ampere is a thousandth of an ampere just as a millimeter is a thousandth of a meter.
The unit of electrical pressure or push is the (ampere) (volt) (watt).
But I admired him, for he had every ampere of his self-possession in hand; my own case was different.
ampere—amperes are units by which the rate of flow of electrical current (electrons) is measured.
An ampere is 6.3 billion electrons passing one point in a circuit, in one second.
Show how to figure the wattage that a circuit protected by a 15 ampere fuse can handle.
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.
