They find applications in radio receiver circuits audio amplifier circuits and tv receivers. The two terminals of the machine are connected to both the ends of the track. Details About Cenco 82910 11 Air Cooled Slide Rheostat 89 Ohms 2 2 Amps Variable Resistor Working Of A Potentiometer Variable Resistor Electrical How To Test Potentiometer Find Bad Potentiometer Leets Variable resistors working the track is usually made of a mixture of ceramic and metal or can be made of carbon as well. Variable resistor working . The third terminal is associated with a wiper that decides the motion of the track. Potentiometers differ from regular resistors in that they have three terminals instead of two. Working principle and construction when we use the term variable resistor it means we are talking about linear resistors by default. These devices are used...
