Hot Selling 22mm 2K 5K 10K Plastic Rotary Potentiometer

A potentiometer is an adjustable electronic component. It consists of a resistor and a rotating or sliding system. When a voltage is applied between the two fixed contacts of a resistor, the position of the contact on the resistor can be changed by rotating or sliding the system, and a voltage that has a certain relationship to the position of the moving contact can be obtained between the moving contact and the fixed contact. It is mostly used as a voltage divider, where the potentiometer is a four terminal element. Potentiometers are basically sliding rheostats, which come in several styles and are commonly used to adjust the volume of a speaker and the power of a laser head. Potentiometers are adjustable electronic components.

The potentiometer can be used as either a three terminal element or a two terminal element. The latter can be regarded as a variable resistor, which is called a potentiometer because its function in a circuit is to obtain an output voltage that is in a certain relationship to the input voltage (applied voltage). Compliance, also known as compliance, refers to the degree of compliance between the actual output function characteristics of the potentiometer and the required theoretical function characteristics. It is expressed as a percentage of the total external voltage with the maximum deviation between the actual and theoretical characteristics, and can represent the accuracy of the potentiometer.
