WebMay 19, 2024 · Most potentiometers have a rotation range of about 270 to 300 degrees, with a typical mechanical resolution and repeatability of around 0.5% and 1% of full-scale value (between one part in 200 and 100, respectively). Note that there is a slight but distinct and important difference between a potentiometer and its junior sibling, the rheostat.
