rheostat
is type two-lead variable resistor and potentiometer a
type three-lead variable resistor.
Rotor The rotating element the magnetic circuit rotating
machine such motor. Double-throw switches are
used transfer loads from one power source another to
transfer power from one load another.
VBII Safety Switiches
General Duty Heavy Duty
. Single-throw safety switches are used provide a
means for disconnecting power.
Fixed Value Resistor Rheostat Potentiometer
Root-mean-square The effective value current voltage.30
Resistor device manufactured have specific amount resistance
or variable within specific range resistance. Root-mean-square is
RMS Value descriptive the mathematical process used calculate the
effective value periodic current voltage.
Safety Switch type enclosed switch that may also include provisions
for fuses
