A diode is connected across the input wires of relays and
solenoid operated
devices, such as valves,
to protect voltage
sensitive navigation and electronic equipment. The diode
is reverse-biased for normal power and no current flows
through the diode. Current flowing through the coil of wire
produces a magnetic field to operate the relay or valve. The
instant power is removed from the coil, the collapsing
magnetic field produces
a momentary spike
of high voltage
which can be several hundred volts depending on the current
and the number of turns of wire in the coil. The diode is
forward-biased
for the power generated
in the coil and the
high voltage spike is dissipated through the diode. A varistor
is used in place of the diode on some relays.
RESISTOR
REGULAR - resistance does not change.
TEMPERATURE CONTROLLED - resistance changes
with the temperature.
VARIABLE OR ADJUSTABLE - resistance changes
with
mechanical
input.
RHEOSTAT
- Type of variable
resistor with two
wires.
