A resistor whose overall ohmic value is fixed; in addition, it has one or more movable terminals which are designed to be set and fixed prior to use, to include any desired value of resistance within the range of the complete resistor. The opposition to the flow of current is an inherent property of the material used and is manifest in the heat dissipated in the item itself.
