Rotary Potentiometers and Rheostats, such as the 91A1A-B28-B10, are electrical components that convert the voltage across them into an output signal. They are used in a wide variety of applications, such as for sensing position, detecting pressure, and controlling the speed of motors. The working principle behind these components is based on the relationship between the electrical resistance within them and the mechanical input applied to them.

The 91A1A-B28-B10 is an example of a rotary potentiometer that measures linear position. This device has a rotation axis and a stationary wiper, which establishes electrical contact between the resistance and the contacts. As the shaft is rotated, the wiper moves along the resistance, changing its resistance value. As the resistance changes, an output voltage is generated that corresponds to the position of the shaft. These potentiometers are commonly used in applications such as motor speed control, instrumentation, and robotics.

Rheostats are another type of electrical component used for various applications as well. A basic rheostat consists of resistors connected in series. The resistance of the rheostat can be adjusted by varying the slider which can be used to create a voltage divider circuit. Unlike the rotary potentiometer, the voltage output of the rheostat does not depend on the position of the wiper. It is instead determined by the amount of current that passes through the device. Rheostats are most often used in applications such as controlling the flow of current in circuits, amplifying signals, and measuring the resistance of a circuit.

In summary, both rotary potentiometers and rheostats are electrical components used in various applications. The principle behind their functioning is based on the relationship between the electrical resistance within the device and the mechanical input applied to it. The 91A1A-B28-B10 is an example of a rotary potentiometer that measures linear position. Rheostats, on the other hand, typically consist of resistors wired in series, and the resistance of the rheostat can be adjusted by varying the slider which can be used to create a voltage divider circuit.
