Ohm’s Law - Expresses the
relationship between Volt (E),
amperes (I) in an electrical
circuit with resistance (R). It can
be expressed as follows: I = V/R
or V = I*R. If any two of the
three values are known, the third
value can be calculated by using
the above formula.
Potable Water - Water that is
safe for human consumption.
Potentiometer - A device for
measuring an unknown potential
difference or electromotive force.
Pounds Per Square Inch Gauge
(psig) -
Pressure measured with respect
to that of the atmosphere. This
is a pressure gauge reading in
which the gauge is adjusted to
read zero at the surrounding
atmospheric pressure. It is
commonly called gauge pressure.
Purge - The initial blast of
air (decompression) from the
air dryer purge valve at the
beginning of the air compressor.
Purge Cycle - The time during
which the air dryer is undergoing
purge and regeneration. This
cycle starts at the beginning of
the compressor unload cycle and
normally ends well before the
beginning of the compressor load
cycle.
Regeneration - The reverse ow
of air through the air dryer and
out the purge valve that begins
immediately after the purge and
lasts normally 10 to 15 seconds.
This reverse ow of air, from
the air system and through the
air dryer, removes moisture
from the desiccant cartridge and
prepares the air dryer for the next
compressor load cycle.
Roadside - The side of the
motorhome that faces the road
while parked. Often called the
off-door side or the driver side.
SCA - Term for Supplemental
Coolant Additive. Chemical
added to coolant for diesel
engines to help prevent cylinder
liner pitting and internal
corrosion.
Shore Line - The electrical cord
which runs from the motorhome
to the campground AC electrical
supply.
Stinger - An arm attachment on
a tow truck that is used to lift the
motorhome slightly for towing.
Volt - The unit of measure for
electric potential.
Watt - The unit for measuring
electrical power, i.e. the rate
of doing work, in moving
electrons by or against an electric
potential.
Wet Cell Battery - A type of
battery that uses liquid as an
electrolyte. This type of battery
requires periodic maintenance to
clean the connections and check
the electrolyte level.
