Rotating potentiometer is a variable resistor (electromechanical component), he relies on the brush to slide on the resistor body, in the circuit to obtain a certain relationship with the input voltage output voltage, so it is called potentiometer.
Since the unit of the resistance value of the rotating potentiometer is the same as that of the resistor, its unit is also ohms
Application:
Rotary potentiometer is mainly used in communication products, walkie-talkies, automotive power amplifier, multimedia audio, smart home, computer peripheral, etc. Its functions are mainly: volume adjustment, light intensity adjustment, menu selection, speed adjustment, temperature adjustment, etc. The main parameters of rotary potentiometer are linearity, resistance value, rated power, rotation noise, temperature, resistance change characteristic, insulation impedance, etc.
