Rotary Potentiometers, Rheostats and 8143R2KL.25

Potentiometers and rheostats are two devices commonly used in electrical circuits. Potentiometers are variable resistors that are built with three terminals, while rheostats are variable resistors that are built with two terminals. Although they are similar in function and applications, they are distinctively different in terms of their construction and size.
