DEFINITION OF TERMS
AC
Common abbreviation for
alternating current.
Alternating Current
A current that is constantly
changing.
AM
Amplitude modulation. The
amplitude of the radio signal is
varied depending on the
information being sent.
Amp
Shortened name for ampere.
Ampere (A)
The unit of measure for electric
current. Commonly shortened
to amp.
Amplitude
Strength or level of something.
Analogy
A similarity in some ways.
AND Gate
A type of digital circuit which
gives a HIGH output only if all of
its inputs are HIGH.
Antenna
Inductors used for sending or
receiving radio signals.
Astable Multivibrator
A type of transistor
configuration in which only one
transistor is on at a time.
Atom
The smallest particle of a
chemical element, made up of
electrons, protons, etc.
Audio
Electrical energy represent-ing
voice or music.
Base
The controlling input of an NPN
bipolar junction transistor.
Battery
A device which uses a chemical
reaction to create an electric
charge across a material.
Bias
The state of the DC voltages
across a diode or transistor.
Bipolar Junction
A widely used type of
Transistor (BJT)
transistor.
Bistable Switch
A type of transistor
configuration, also known as the
flip-flop.
Capacitance
The ability to store electric
charge.
Capacitor
An electrical component that
can store electrical pressure
(voltage) for periods of time.
Carbon
A chemical element used to
make resistors.
Clockwise
In the direction in which the
hands of a clock rotate.
Coil
When something is wound in a
spiral.
In electronics this
describes inductors, which are
coiled wires.
Collector
The controlled input of an NPN
bipolar junction transistor.
Color Code
A method for marking resistors
using colored bands.
Conductor
A material that has low
electrical resistance.
Counter-Clockwise
Opposite the direction in which
the hands of a clock rotate.
Current
A measure of how fast electrons
are flowing in a wire or how fast
water is flowing in a pipe.
Darlington
A transistor configuration which
has high current gain and input
resistance.
DC
Common abbreviation for direct
current.
Decode
To recover a message.
Detector
A device or circuit which finds
something.
Diaphragm
A flexible wall.
Differential Pair
A
type of transistor
configuration.
Digital Circuit
A wide range of circuits in which
all inputs and outputs have only
two states, such as high/low.
Diode
An electronic device that allows
current to flow in only one
direction.
Direct Current
A current that is constant and
not changing.
Disc Capacitor
A type of capacitor that has low
capacitance and is used mostly
in high frequency circuits.
