One could just insert potentiometer (regular, not so scary) to feedback circuit of ATX power supply instead of resistor, using this modification one could achieve regulating of output voltage, and ...

Analog Devices has introduced the world’s first digital potentiometer with ±1% end-to-end resistor tolerance in response to a market requirement for tighter tolerance.

Potentiometers aren’t all rotating components though. They can also be sliders, as shown in the photo of an equalizer on a keyboard. These are prone to dirt getting inside them and interfering ...

If the application requires a linear response, the digital potentiometer can be linearized either by using the digital potentiometer in rheostat mode (Fig. 3(b)), a Vernier DAC configuration (Fig ...

A parallel resistor/potentiometer combination gives a non-linear response. Using a log taper potentiometer does not correct this anomaly, but it changes the curve such that the light output appears ...

You can use a photoelectric FET as a variable resistor or a potentiometer in combination with a fixed resistor. The H11F3M photoelectric FET has an isolation voltage of 7.5 kV, enabling you to safely ...
