Variable resistors are resistors used to change resistance from zero to a certain maximum value. They are commonly used as volume switch and in voltage regulators. It has three terminals: positive, ground, and negative. Variable resistors can be categorized broadly into three types: Potentiometer – uses three terminals and is used as a potential divider […]View more at https://www.circuitbasics.com/variable-resistors/.
