Introduction to Potentiometers (variable resistors, or trimmers)

Potentiometers are variable resistors. The resistance changes when the wiper is adjusted. The variable resistance is measured from one of the outside leads to the center (wiper) lead. The small variable resistors are generally called trimmers.
