The pot is a variable resistor that allows the ratio of the two resistors to change in a complementary and continuous fashion. That is, as one resistor increases in value the other resistor is made to ...

A resistor is characterized by an always constant resistive value. With the same applied voltage, it will always pass the same amount of current. The potentiometer, on the other hand, is an electronic ...

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 ...

[Lee] wrote in to share the work he’s done in building a controller for his soldering iron. The idea started when he was working with an ATX power supply. He figured if it works as a makeshift bench ...

Digital potentiometers are digitally controlled variable resistors that can be used in place of their functionally equivalent mechanical counterparts. While digital potentiometers offer comparable ...

Digitally controlled potentiometers (DCPs) have become very popular in a wide variety of applications including control, parameter adjustment, and signal processing. The digital pots replace ...

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 ...
