What is Trimmer Potentiometer
Trimmer potentiometer is a resistor that can be adjusted or "trimmed" to a precise resistance by turning a screw. This type of resistor is often used in circuits because it allows adjustment of circuit performance. Use a tool (such as a screwdriver) to turn the dial or knob on the device to adjust. Trimmer resistor symbols are shown below.
