A new breed of electronically adjustable resistors promises to ease fine-tuning in sensors and other electronic devices. Adjustable resistors have come a long way from mechanical potentiometers set ...
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 ...
