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 ...

I think poteniometers are very similar to rheostats, and the only rheostat in the Jameco catelog is $23, so I was wondering if I could use a $3 5 watt potentiometer instead for controlling voltage ...

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 ...

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.

A programmable rheostat approach that minimizes both op-amp performance requirements and worst-case errors. Aspencore network. ... Yes, it’s slightly simpler in that it avoids MOSFETs, and that the ...

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 ...

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 ...
