Alternating Current (AC)
A flow of electricity which reaches maximum in one
direction, decreases to zero, then reverses itself and
reaches maximum in the opposite direction. The cycle is
repeated continuously. The number of cycles per second
is equal to the frequency.
Ambient Temperature
The temperature of the atmosphere of surrounding
environment. Typically defined by industry standards as
25 C.
Amp (Ampere)
A unit that measures the strength/rate of flow of
electrical current.
Anode
The positive electrode or terminal of a device. The "P"
material of a diode.
Armature
The portion of the magnetic structure of a DC or
universal motor which rotates.
Capacitor
An electrical device used to store electrical energy, and
to release it back into the power system when required.
Cathode
The negative terminal electrode of a device. The "N"
material in a junction diode.
Chassis
Metal box or frame into which components are mounted.
A hermetically sealed motor which pumps refrigerant
throughout system.
A tubing coil, which refrigerant flows through, that is
designed to remove heat from the refrigerant, changing
its state from a high pressure vapor to a high pressure
liquid.
A two terminal device that conducts in only one direction.
Direct Current (DC)
A constant value current that flows in only on direction.
Double-Pole, Double-Throw (DPDT) Switch
A switch that makes or breaks the connection of two
conductors to two separate circuits. This switch has six
terminal screws and is available in both momentary and
