Refers to the how much current a wire can safely carry. For example, a 12 gauge electrical copper wire can safely carry up to 20 amps.
Amperage
The strength of an electrical current measured in amperes.
Ampere
A unit of measure for an electrical current; the amount of current that flows in a circuit at an electromotive force of one Volt and at a resistance of one Ohm. Abbreviated as amp.
Ampere-hour
Standard unit for measuring the quantity of electricity; equal to the flow of a current of one ampere for on hour or to an elapsed current drain of 3,600 coulombs.
Ampere-turn
Amount of magnetomotive force produced by an electric current of one ampere flowing around one turn of a wire coil.
Amphibious
The ability of plants to brow both in aquatic and in the exposed soil. Usually in a moist or boggy condition, when the winter recedes in the area.
Amphitheater
Round or oval building with open space surrounded by rising rows of seats, which is often used for shows, lectures and other activities performed for an audience.
Amplidyne
Direct-current generator which using a small amount of direct current (DC) power applied to its field windings to control the generator's output.
Amplification
An increase in the numbers or concentration of a microbe or its products through reproduction and growth of the microbe.
Amplifier
Device with electron tubes or semiconductors, which is used to increase the strength of an electrical signal.
