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