A potentiometer, also known as a variable resistor or rheostat, is an electronic device that functions as a voltage divider to measure electric potential (voltage). This component, often depicted in 3D files for PCB design, can be utilized in various applications including controlling electrical devices such as volume controls on audio equipment. Moreover, mechanically operated potentiometers serve as position transducers, for instance, in joysticks.
