2. Potentiometer - Wikipedia

   en.wikipedia.org/wiki/Potentiometer

   A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. [1] If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.

3. Trimmer (electronics) - Wikipedia

   A: preset resistor, B: preset resistor (alternate), C: preset potentiometer, D preset potentiometer (alternate), E: preset inductor, F: preset capacitor. In circuit diagrams, the symbol for a variable component is the symbol for a fixed component with a diagonal line through it terminating in an arrow head.

4. Resistor - Wikipedia

   en.wikipedia.org/wiki/Resistor

   A potentiometer (colloquially, pot) is a three-terminal resistor with a continuously adjustable tapping point controlled by rotation of a shaft or knob or by a linear slider. [23] The name potentiometer comes from its function as an adjustable voltage divider to provide a variable potential at the terminal connected to the tapping point. Volume ...

   A potentiometer (colloquially, pot) is a three-terminal resistor with a continuously adjustable tapping point controlled by rotation of a shaft or knob or by a linear slider. [14] The name potentiometer comes from its function as an adjustable voltage divider to provide a variable potential at the terminal connected to the tapping point. Volume ...

8. Voltage divider - Wikipedia

   en.wikipedia.org/wiki/Voltage_divider

   Another example that is commonly used involves a potentiometer (variable resistor) as one of the resistive elements. When the shaft of the potentiometer is rotated the resistance it produces either increases or decreases, the change in resistance corresponds to the angular change of the shaft.

9. 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.
