Common use of potentiometers

The potentiometer can adjust the voltage division ratio and change the potential. It is equivalent to an electronic component that can be adjusted. The English symbol is Rp. The potentiometer is derived from the development of a variable resistor. It is composed of a resistor and a rotation. The sliding system is composed of a movable arm contact brush sliding on the resistor body, which can continuously change the negative value between the movable arm and both ends.


precautions for using potentiometer


The resistance value of the potentiometer is generally not recommended to be adjusted up or down, or it will affect the operation performance of the potentiometer, and thus it is easy to cause the anti-interference ability of the potentiometer to deteriorate. Therefore, the use of potentiometers will be greatly affected.


When the potentiometer works frequently, pay attention to the detection quality of the potentiometer to see if there is a fault. For the operation power of this type of potentiometer, it is not suitable for small, and the power of the general potentiometer is not suitable for some. Use of small venues.


The resistance of the potentiometer generally should not exceed its standard 1010KΩ, otherwise the connection between the internal circuits of the potentiometer will not match each other, resulting in damage to the potentiometer.
