A preset resistor is used in some circuits to change the resistance. The preset resistor enables the circuit to be more or less sensitive thereby altering the resistance.

How connect a variable resistor to circuit?

To connect a variable resistor to a circuit, identify the two terminals of the variable resistor. Connect one terminal to the input or output of the circuit where you want to adjust the resistance. Connect the other terminal to either the ground or another reference point depending on the circuit's design. Ensure that the resistance value on the variable resistor is adjusted as needed for your circuit application.
