WEET Why Choose A 3386P Potentiometer? Top 4 Uses In Electronic Circuits
WEET 3386P breadboard trim potentiometer is an adjustable resistor, whose core function is to flexibly regulate voltage, current, or signal amplitude in a circuit.
Its common application scenarios are classified as follows :
Current Limiting
When only one fixed pin and the middle pin are connected, finger adjust preset pot functions as an adjustable resistor to limit the current in the circuit.
Example: Adjusting the brightness of LEDs
Signal Adjustment
Finger adjust preset pot is used in signal circuits such as audio and radio frequency (RF) circuits to adjust signal amplitude or attenuation.
Example: Volume knob of a radio
3Circuit Calibration
In circuits requiring precise parameter matching, it is used to fine-tune resistance values to optimize the circuit's working performance.
Example: Calibrating the zero point of measuring instruments
Voltage Dividing (Most Commonly Used)
When finger adjust preset pot connected between the power supply and ground, the middle pin can output an adjustable voltage.
