Rotary potentiometers and rheostats can both be classified as variable electrical resistances. However, they are distinct components, and the 91A1A-B28-A22L is no exception. This device falls into the category of rotary potentiometers, which are a subset of the larger family of variable resistances.

The 91A1A-B28-A22L is essentially an adjustable resistance element with a contact wiper. It is capable of generating a variable voltage output based on the amount of resistance being passed through. This is done through the resistive track, which is a circular configuration of conductive and resistive material. In general, the higher the resistance within the resistive track, the lower the output voltage produced.

The 91A1A-B28-A22L is typically used as a volume control in various electronic devices. The user adjusts the resistance within the resistive track, thereby adjusting the output voltage, and in turn, the volume of the device. This is possible because the resistance within the track is adjustable, which is what makes it a potentiometer. It is important to note that the resistive track is not a continuous loop, but rather is broken up into discrete steps. This means that the user can select the desired resistance value, and also adjust the output voltage accordingly.

In addition to its use as a volume control, the 91A1A-B28-A22L can also be used as a variable resistor. By simply changing the amount of resistance within the resistive track, the device can be used to adjust the power output of a circuit. This is useful in a wide variety of applications, such as in power supplies, motor speed controllers, and dimmer switches.

Rotary potentiometers and rheostats both serve distinct purposes within electronic circuits. The 91A1A-B28-A22L is a potentiometer, making it suitable for use as a volume control, as well as a variable resistor. As an adjustable resistance element, it is capable of producing a variable voltage output based on the amount of resistance it passes through its resistive track. This particular device is most commonly used in consumer electronics, however, it could theoretically be used in any application where a variable resistance might be necessary.
