Variable Resistor Function
When only two terminals are used it functions as a variable resistance and is called a rheostat. As the circuit works resistors dissipate heat which is not used. How Variable Resistors Work Circuit Basics The first main function of a variable resistor is its ability to adjust current. . They specifically work with voltage and currents that are a part of the circuit. The third terminal is attached to a wiper that controls the tracks movement. A variable resistor has a resistance channel that is provided by a track. A variable resistor is in essence an electro-mechanical transducer and normally works by sliding a contact wiper over a resistive element. The third terminal is connected to a wiper that decides the movement of the track. Simply put a variable resistor can have its electrical resistance adjusted. Simply put a variable resistor is able to have its electrical resistance adjusted. Ad Order Power Thr...
