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.
The 'log pot', that is, a potentiometer has a resistance, taper, or, "curve" (or law) of a logarithmic (log) form, is used as the volume control in audio power amplifiers, where it is also called an "audio taper pot", because the amplitude response of the human ear is approximately logarithmic. It ensures that on a volume control marked 0 to 10 ...
Integrated circuit (IC) shorter "U" (unit) is preferred instead of "IC" V: Vacuum tube: VR: Voltage regulator (voltage reference), or variable resistor (potentiometer / trimmer / rheostat) voltage regulators are often "U" for IC, pots and trimmers often "R" for resistor X
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 ...
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 ...
Common circuit diagram symbols (US ANSI symbols) An electronic symbol is a pictogram used to represent various electrical and electronic devices or functions, such as wires, batteries, resistors, and transistors, in a schematic diagram of an electrical or electronic circuit. These symbols are largely standardized internationally today, but may ...
