Potentiometer introduction
Potentiometer is a kind of variable resistor.
The resistor body is composed of a rotating or sliding system, that is, a moving contact moves on the resistor body to obtain a partial voltage output.
The role of the potentiometer-adjust the voltage (including DC voltage and signal voltage) and the size of the current.
The structural characteristics of the potentiometer-the resistor body of the potentiometer has two fixed ends. By manually adjusting the rotating shaft or slider to change the position of the moving contact on the resistor body, the moving contact and any fixed end are changed. The value of the resistance changes the magnitude of voltage and current.
Potentiometer is an adjustable electronic component. It is composed of a resistor and a rotating or sliding system. When a voltage is applied between the two fixed contacts of the resistor body, the position of the contact on the resistor body can be changed by rotating or sliding the system, and a moving contact position can be obtained between the moving contact and the fixed contact Voltage. It is mostly used as a voltage divider, then the potentiometer is a four-terminal . The potentiometer is basically a sliding rheostat. There are several styles. It is generally used in the volume switch of the speaker and the power adjustment of the laser head. The potentiometer is an adjustable electronic component.
Variable resistor for voltage division. One to two movable metal contacts are pressed tightly on the bare resistor body. The position of the contact determines the resistance between either end of the resistor and the contact. According to the material, it is divided into wire winding, carbon film, solid core potentiometer; according to the relationship between the output and input voltage ratio and the rotation angle, it is divided into linear potentiometer (linear relationship) and function potentiometer (curve relationship). The main parameters are resistance, tolerance and rated power. Widely used in electronic equipment, used for volume control in audio and receiver.
