Application of Timmer Potentiometer
Trimmer potentiometer is also called trimmer resistor or variable resistor that allows you to manually fine-tune the resistance in a circuit. It is usually used for calibration in applications for amplifiers and radios to assure that the circuit output is as close to the ideal level as possible.
