Adjustable Power Resistor

Potentiometers, Variable Resistors/Adjustable Power Resistor.Adjustable Power Resistors are a user configurable device that opposes the flow of current in an electrical circuit. The resistance of these devices can be changed by moving a central terminal between the two solder lug terminals at the ends of the resistor body. Overall device length can range from 2 inches to 12 inches and have power ratings of up to 500 watts.
