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 ...

Sometimes it is useful to have a variable resistor that can be controlled via a microcontroller, even if the adjustment resolution is not very fine. Often, as few as 16 steps are adequate (e.g., for ...

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 ...

Resistor with simple electric circuit scheme. Physical test for education in schools at physics lesson. Rheostat is an electrical instrument used to control a current by varying the resistance.

Abstract: The floating node voltage-controlled linear variable resistor circuit is a versatile building block in several analog signal processes such as telecommunications and electronics. Floating ...

Abstract: A linear voltage controlled variable resistor in partially depleted silicon-on-insulator (PD-SOI) technology is presented. Stacked FET structure is utilized for the variable resistor ...

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 ...

Moving the position of the slider on this resistor, changes the length of wire in the circuit which changes the resistance. A variable resistor is used in some dimmer switches and volume controls. As ...
