Rotary Potentiometers, Rheostats, are electronic components that contain a wiper, a resistive element and a user interface that facilitates the adjustment of the resistive element. The most common type of rotary potentiometer is the 91R1A-R22-B25L.

The 91R1A-R22-B25L is an adjustable resistor that can be used to adjust the resistance in an electronic circuit. It consists of a rotating shaft, a wiper contact and a resistive element. The turning of the shaft adjusts the position of the wiper contact relative to the resistive element thus varying the resistance of the circuit. This can be used to regulate current in a circuit or to create logarithmically changing resistance either as a voltage divider or a voltage controlled resistor.

The 91R1A-R22-B25L is often used in audio equipment, where it is used to control the level of gain or the tone of an audio signal. It can also be used in power supplies and regulating circuits, where it is used to regulate the output voltage or current. Additionally, they can be used in devices such as radios, televisions, and computers to adjust the contrast, volume, and brightness.

The 91R1A-R22-B25L works on the principle of changing the resistance of the circuit. As the shaft is turned, the wiper contact moves along the length of the resistive element. This changes the conductive path of the circuit, allowing more current to flow through parts of the circuit and less in others. This causes the resistance of the circuit to change, resulting in the desired effect.

The 91R1A-R22-B25L is a reliable and useful device for controlling the resistance in an electronic circuit. It is highly customizable and can be used in many applications, such as audio equipment, power supplies and regulating circuits, televisions, and radios. The adjustable feature enables the user to control the output of these devices more precisely than with fixed resistors, allowing for more accurate results.
