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 ...

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 ...

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 ...

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, ...

Resistor symbol (U.S. and Japan). where P is the power in watts, V is the voltage in volts, and R is the resistance in ohms. Types of resistors Fixed resistors. A fixed resistor is one in which the ...

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 ...

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 ...
