Potentiometer is a type of variable resistor. The composition of the potentiometer consists of a resistor body and a rotating or sliding system.
The role of the potentiometer - adjust the voltage (including DC voltage and signal voltage) and the magnitude of the current.
1. Used as a voltage divider
The potentiometer is a continuously adjustable resistor. When the knob or slider of the potentiometer is adjusted, the movable contact slides on the resistor body. At this time, an output voltage which is related to the potentiometer applied voltage and the movable arm angle or stroke can be obtained at the output end of the potentiometer.
2. Used as a varistor
When the potentiometer is used as a varistor, it should be connected to the two ends of the device, so that a smooth and continuously changing resistance value can be obtained within the stroke range of the potentiometer.
3. Used as a current controller
When the potentiometer is used as a current controller, one of the selected current outputs must be the sliding contact terminal.
Potentiometers, which are widely used as electronic components, are extremely valuable in recycling. recycle various types of potentiometer. Please fell free to contact us if you have excess inventory.
