Brand new and high quality Feature: A potentiometer is a type of variable resistor, usually composed of a resistor body and a rotating or sliding system. A moving contact is moved on the resistor body to obtain a partial voltage output, making it an adjustable electronic component. When a voltage is applied between the two fixed contacts of the resistor body, the position of the resistor body is changed by the rotation or sliding system, creating a positional relationship between the movable contact and the fixed contact. Most commonly used as a voltage divider, when configured as a four-terminal component, the potentiometer functions as a sliding rheostat. It is generally used in speaker volume controls and laser head power adjustments.
