Single-pole potentiometer
A single-pole potentiometer is a synchronous regulating potentiometer made of a resistive substrate. Its function in the circuit is to obtain an output voltage that is related to the input voltage (external voltage) in a certain way, hence it is called a potentiometer. The sliding resistor is a commonly used potentiometer in laboratories. This potentiometer is large in size, has high power, and the sliding part is visually intuitive. It can also be used as a current limiter.

Dual potentiometer
What is a dual potentiometer? A dual potentiometer is actually a combination of two independent potentiometers. In a circuit, it can adjust two different operating point voltages or signal intensities. For example, the volume control potentiometer in a dual-channel audio amplifier circuit is a dual potentiometer that can separately adjust the volume of both channels.
