Ampere (a)

[1] A unit of measure for current. [2] 1 Coulonb of electrons or 6.28x10 /18th electrons passing a single point in one second [3] Names for Andre Ampere (1775 - 1836 )

Ampere - Turns

A measure of the magnetic field produced by a coil of wire with current flowing through it. Equal to amperes of current flow multiplied by the number of turns of wire on the coil.

Ampere, Andre Marie

b. 1775, d.1836; a teacher at paris, has his permanent place in the history of science as it was his name that was chosen for the unit by which we measure electrical current.

Amplification

An increase in signal amplitude during its transmission from one point to another.

Amplifier

A device consisting of one or more vacuum tubs, transistors, or magnetic devices and associated components to increase the strength of the applied signal.

Amplitude

[1] The difference between the highest and lowest voltage displayed [2] The magnitude of an electrical signal above or below some reference, usually measured in voltage above or below "0".

Amplitude Modulation (am)

A technique for impressing information upon a carrier by varying the amplitude of the carrier.

Amv

Air management valve.

Anaerobic Sealants

A chemical sealant placed on a gasket in an engine to aid in sealing and to position the gasket during installation.

Anaerobic Sealer

Liquid or gel that bonds two parts together in the absence of air.

Analog

[1] Continously Variable [2] A signal that varies in amplitued continuously and without interruption.

Analog Computer

A computer that measures continuously changing conditions, such as temperature and pressure, and converts them into quantities.

Analog Instrument

An instrument having a needle on a dial used for taking measurements, such as temperature and engine RPM.

Analog Signal

An electrical signal that varies in amplitude within a given parameter.

Analog-to-digital Converter

Electrical device used to convert continuous analog signals to a digital code that represents the amplitude of the original signal sample.

Anaroid Tube

A thermo-mechanical device in a fuel-injection system that regulates the amount of fuel being injected according to differences in temperature and pressure in the intake manifold.

Anchor

1. A Slang expression for brakes. 2. A mounting point on a vehicle structure for a stressed, non-structural component, such as a seat belt or a seat.

Anchor End

That end of a brake shoe that is attached to a fixed point on the backing plate.

Anchor Pin

A steel pin rigidly attached to the backing plate of drum brakes. Return springs are attached to the anchor pin and to the brake shoes to hold the shoes against the anchor pin in a non-applied position. In an applied position, it prevents the shoes from rotating with the drums.

Anchors

Performance term for brakes.
