An electronic component that is used to vary the amount of current that flows through a circuit. It works by sliding a wiper terminal across a resistive material, typically a thin film or chunk of ...

Adjusting the volume dial on a sound system, sensing your finger position on a touch screen, and knowing when someone’s in the car are just a few examples of where you encounter variable resistors in ...

Why get up close and personal with a resistor when you can tweak it from a distance? Remote variable resistors make analog circuit control easier, neater, and a lot more fun. Well, we are about to ...

A variable resistor that integrates a programmable, temperature-indexed look-up table can compensate for the temperature drift of a voltage regulator. In this case, the look-up table can change the ...

The VRH320 Variable Wire Wound Resistor available from ARCOL Resistors has a wide range of applications for voltage and current adjustment including industrial machinery RPM adjustment, instruments, ...

For the pdf version of this article, click here. Click to read part II and part III of this article. Very often when simulating an electrical circuit in SPICE, there is a need for a variable passive ...

If you need a potentiometer for a project, chances are pretty good that you’re not going to pick up a pencil and draw one. Then again, if you’re teaching someone how a variable resistor works, that ...
