RV09 Potentiometer 5pcs Variable Resistors Single Turn Adjustable Rotary Taper Potentiometer With Knob -1K vertical-7.5mm

A potentiometer is a type of variable resistor, usually composed of a resistor body and a rotating or sliding system, that is, a moving contact is moved on the resistor body to obtain a partial voltage output, which is 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, and a position relationship with the position of the movable contact is obtained between the movable contact point and the fixed point. The voltage, which is mostly used as a voltage divider, when the potentiometer is a four-terminal component, the potentiometer is basically a sliding action rheostat, generally used in the speaker volume switch and laser head power size adjustment. Specifications: Resistance: 1K/2K/5K/10K/20K/50K/100K
