A potentiometer is a passive electronic component. Potentiometers work by varying the position of a sliding contact across a uniform resistance. In a potentiometer, the entire input voltage is applied across the whole length of the resistor, and the output voltage is the voltage drop between the … See more There are two main types of potentiometers: 1. Rotary potentiometer 2. Linear potentiometer Although the basic constructional features of these potentiometers vary, the working principle of both of these … See more Digital potentiometers are three-terminal devices, two fixed end terminals and one wiper terminal which is used to vary the output voltage. Digital potentiometers have various applications, including calibrating a system, adjusting … See more A potentiometer gives variable voltage. A rheostat gives variable resistance.
