The principle of a potentiometer is that the potential dropped across a segment of a wire of uniform cross-section carrying a constant current is directly proportional to its length. The potentiometer is a simple device used to measure the electrical potentials (or compare the e.m.f of a cell).
A potentiometer with a resistive load, showing equivalent fixed resistors for clarity. The potentiometer can be used as a voltage divider to obtain a manually adjustable output voltage at the slider (wiper) from a fixed input voltage applied across the two ends of the potentiometer. This is their most common use.
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 ...

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 ...
A Texas teen is accused of killing a classmate’s show goat by force-feeding it pesticide. Aubrey Vanlandingham, 17, is charged with cruelty to livestock animals, a felony, according to court ...
An Indiana school bus driver was busted for allegedly driving under the influence — with some of the 32 kids on her bus calling in to report her driving them erratically, authorities said.
Motorized potentiometers can be found in audio/video equipment, specifically mixing consoles. [1] In this application, they are called motorized faders. Mixing consoles with motorized faders typically are used to save and restore settings on the same console and sometimes to transfer settings to a different console.
