A rotary potentiometer, also known as a “Rheostat”, is an electronic component used to measure or control electrical signals. The 91R1D-R22-B20L is a type of rotary potentiometer that is used in a variety of different applications and is commonly used to measure voltage, current, and resistance. This article will discuss the application field and working principle of the 91R1D-R22-B20L.The 91R1D-R22-B20L is a three-wire rotary potentiometer that can be used in a variety of different applications. It is commonly used to measure and control voltage, current, and resistance. The 91R1D-R22-B20L has a wide range of resistance values ranging from 0 to 5k ohms.The 91R1D-R22-B20L is typically used in circuits where the user needs to control the analog signal, such as in motor or light dimmer controllers. It can also be used to measure electrical signals such as voltage, current, and resistance during circuit testing.In order to understand how the 91R1D-R22-B20L works, it is important to understand the working principle of a rotary potentiometer. A rotary potentiometer is a three-wire device that is composed of a central spindle, two terminals, and a resistor network. When the central spindle is turned, it will cause a change in the resistance between the two terminals. This change in resistance is then transmitted as an electrical signal that can be used to measure or control the electrical signals in the circuit.The 91R1D-R22-B20L can be used as a rheostat, or a variable resistor, to measure or control electrical signals in a circuit. When used as a rheostat, the user can adjust the resistance value of the 91R1D-R22-B20L by turning the central spindle. This will cause the resistance value between the two terminals to change, thus resulting in an increase or decrease in the electrical signal being measured.The 91R1D-R22-B20L can also be used as a potentiometer, or a fixed resistor. In this application, the user can adjust the resistance value of the 91R1D-R22-B20L by changing the number of turns of the central spindle. This will result in a change in the voltage or current of the electrical signal being measured.In conclusion, the 91R1D-R22-B20L is an electronic component used to measure or control electrical signals in a variety of different applications. The 91R1D-R22-B20L can be used as a rheostat or potentiometer in order to measure and control voltage, current, and resistance. Understanding the working principle and application field of the 91R1D-R22-B20L can help the user to better understand their circuits and troubleshoot any problems they may encounter.
