About This Product
Moving the slider changes how much of the winding is in the circuit, so the current can be set smoothly from the full resistance down to zero. Used as a variable resistor or, with all three terminals, as a potential divider, it is a standard part of Ohm’s law experiments and bridge circuits. The 25 OHM VARIABLE RESISTOR can be supplied on export terms to Laos, South Sudan, Mongolia, Zimbabwe and Albania.
Frequently Asked Questions
What current can the 25 Ohm Variable Resistor carry?
It is rated for 2.8 amperes on continuous load.
Why does it have three terminals?
Two terminals connect to the ends of the winding and the third to the slider, so it can be wired as a variable resistor or a potential divider.
