Resistors

pot

common short term for potentiometer

variable resistor

resistor whose resistance value can be changed between its minimum and maximum values

wire-wound resistor

resistors cpmstricted by winding resistive wires around a nonconductive material.

metal glaze resistor

resistors produced by applying a mixture of metal and glass to a nonconductive material

metal film resistor

resistors produced by coating a nondonductive material with a film of metal

fixed resistor

resisitors with a value that cannot be changed

composition carbon resistor

resistors that are made by mixing carbon with other compounds to produce a substance that has a known resistance

voltage divider

a circuit constructed by connecting resistors in series to produce voltage drops across the resistors

carbon film resistor

a resistor produced by coating a nondonductive material with a film of carbon

color code

a system where colors are used to represent numbers

rheostat

a variable resistor

tolerance

amount of variation that is permissible from a standard value

short circuit

an electric circuit that contains no resistance to limit the flow of current

multiturn variable resistor

resistors that require multiple turns to change their resistance value, used where precise control of resistance value is critical.

potentiometer

variable resistor with a sliding contact that is used as a voltage divider
