2. Potentiometer - Wikipedia

   en.wikipedia.org/wiki/Potentiometer

   Linear taper potentiometers [4] are used when the division ratio of the potentiometer must be proportional to the angle of shaft rotation (or slider position), for example, controls used for adjusting the centering of the display on an analog cathode-ray oscilloscope. Precision potentiometers have an accurate relationship between resistance and ...

3. Trimmer (electronics) - Wikipedia

   en.wikipedia.org/wiki/Trimmer_(electronics)

   The skeleton potentiometer works like a regular circular potentiometer, but is stripped of its enclosure, shaft, and fixings. The full movement of a skeleton potentiometer is less than a single turn. The other type is the multi-turn potentiometer which moves the slider along the resistive track via a gearing arrangement. The gearing is such ...

4. Guitar wiring - Wikipedia

   A diagram showing the wiring of a Gibson Les Paul electric guitar. Shown are the humbucker pickups with individual tone and volume controls (T and V, respectively), 3-way pickup selector switch, tone capacitors that form a passive low-pass filter, the output jack and connections between those components. The top right shows a modification that ...

5. Battery simulator - Wikipedia

   en.wikipedia.org/wiki/Battery_simulator

   For example, the user selects the voltage of the battery to be simulated, using the potentiometer knob for adjusting the voltage, while the current value is displayed on the digital screen. An independent potentiometer is available to select the maximum current that the equipment can source or sink. [2] [failed verification]

6. Voltage divider - Wikipedia

   en.wikipedia.org/wiki/Voltage_divider

   Voltage dividers are used for adjusting the level of a signal, for bias of active devices in amplifiers, and for measurement of voltages. A Wheatstone bridge and a multimeter both include voltage dividers. A potentiometer is used as a variable voltage divider in the volume control of many radios.

7. Potentiometer (measuring instrument) - Wikipedia

   en.wikipedia.org/wiki/Potentiometer_(measuring...

   A potentiometer being calibrated and then measuring an unknown voltage. R 1 is the resistance of the entire resistance wire. The arrow head represents the moving wiper.. In this circuit, the ends of a uniform resistance wire R 1 are connected to a regulated DC supply V S for use as a voltage divider.

8. Digital potentiometer - Wikipedia

   en.wikipedia.org/wiki/Digital_potentiometer

   While quite similar to normal potentiometers, digital potentiometers are constrained by current limit in the range of tens of milliamperes. Also, most digital potentiometers limit the voltage range on the two input terminals (of the resistor) to the digital supply range (e.g. 0–5 VDC), so additional circuitry may be required to replace a conventional potentiometer, (although digital ...

9. Potentiostat - Wikipedia

   en.wikipedia.org/wiki/Potentiostat

   A potentiostat is a control and measuring device. It comprises an electric circuit which controls the potential across the cell by sensing changes in its resistance, varying accordingly the current supplied to the system: a higher resistance will result in a decreased current, while a lower resistance will result in an increased current, in order to keep the voltage constant as described by ...
