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.
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.

Resistor: RN: Resistor network: sometimes simplified to "R" for resistor, or "N" for network RT: Thermistor: sometimes simplified to "R" for resistor RV: Varistor, variable resistor: S: Switch (all types, including buttons) sometimes "SW" is erroneously used SA: Spark arrester: T: Transistor
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.
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.
