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 ...

Power resistors, rheostats (variable resistors), and other electrical loads are useful for testing power supplies and regulators. Though functionally equivalent to a mechanical rheostat, electronic ...

Here is a simple mod to allow the speed of any 12V fan to be varied. All we need to do is insert a rheostat or variable resistor in the 12V wire to the fan. The rheostat should be rated at least 3 ...

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 ...

Integrating voltage dividers and networks into common packages, rather than selecting discrete resistors, can ultimately produce analog circuits with better performance and reliability. As a matter of ...
