IV Features of Variable Resistor Shape (1) The volume of the variable resistor is larger than that of the general resistor, and at the same time, the variable resistor in the circuit is less, and it can be easily found in the circuit board. (2) There are three pins in the variable resistor, and they are different from each other. One is a moving pin and the other two are fixed. Generally, the two fixed pins can be used interchangeably, but the fixed and moving pin cannot be used interchangeably. Variable resistor Types of variable resistor Variable resistor overview. As the name implies, the resistance of the variable resistor is changeable. It is easy to vary or change the resistance of a variable resistor to a desired value. Variable resistors are mostly used when the user do not know what exact resistance value does he want.
