Ambient Temperature The temperature of the medium (such a air) surrounding a
device.
American National A nongovernmental organization that promotes and coordinates
Standards Institute (ANSI) the development of standards and accredits the procedures of
other organizations that develop standards.
American Wire Gauge A common method of specifying wire size (cross-sectional
(AWG) area). Larger numbers represent smaller wires. After AWG No. 1,
the largest sizes are AWG No. 0, AWG No. 00, AWG No. 000, and
AWG 0000. AWG No. 0 is called one-aught, AWG No. 00 is called
two-aught, etc.
Ammeter A meter designed to measure current.
Ampacity The continuous current rating in amperes for a conductor.
Ampere, Amp The basic unit for current. An ampere, also called an amp, is
equal to a current of 1 Coulomb per second. The symbol for
ampere is “A.”
Amplitude The total variation of a waveform. Amplitude can be expressed
as a peak value, peak-to-peak value, or effective value.

Analog A value that is continuously variable. Also used to describe
circuits that work with analog signals.
Analog Input An input to a system that can continuously vary over a range of
current or voltage such as 4 to 20 milliamps or 0 to 10 volts.
