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 ...

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 ...

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 ...

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 ...
