Overview of piher spain 10k potentiometer            

On the bare resistor, one or two movable metal contacts are pressed tightly. The contact position determines the resistance between any end of the resistor and the contacts. When a voltage is applied between the two fixed contacts of the resistor, the position of the contacts on the resistor is changed by rotating or sliding system, and a voltage which is related to the position of the moving contacts can be obtained by rotating the contacts and the fixed contacts. The potentiometer is basically a sliding rheostat. There are several types of potentiometers, which are commonly used in loudspeaker volume switches and laser head power adjustment.            

Sliding rheostat commonly used in junior high school electrical experiment is a common wire wound potentiometer.            Usage of piher spain 10k potentiometer             

This circuit has positive and negative symmetrical power supply. For example, when the central contact C of the potentiometer slides to the potentiometer A terminal, the output voltage of OUT is + 12V, and when the central contact C of the potentiometer slides to the potentiometer B terminal, the output voltage of OUT is - 12V.            

Single power supply control potentiometer, output C has 0- V regulation range.            

This is a connection of audio amplifier for volume control. It has the largest volume when the central contact C of the potentiometer slides to potentiometer A. It has the lowest volume when the central contact C of the piher spain 10k potentiometer to potentiometer B. If the contact between the central contact C and B is not good, the volume will not shut down.
