Rotary Potentiometers and Rheostats are electrical components used to produce a continuous variation in an output voltage or current, usually over a wide range of resistance values. The 91A2A-B28-B18/B18L is a rotary potentiometer-rheostat used to adjust the current or voltage of an electric circuit.The 91A2A-B28-B18/B18L is a high power, low resistance rotary potentiometer, designed for switching and adjusting circuits. It consists of two main components: the outer shell, which is held in place by three metal nuts, and the resistance element, which is referred to as a rheostat. The resistance element is a flat wafer-like structure covered with a thin layer of resistance material, such as nickel, copper, or gold.The 91A2A-B28-B18/B18L can be used to adjust the output of a circuit, or to reduce its power consumption. For example, it can be used to adjust the brightness of an LED light, or to reduce the power consumption of a motor. It can also be used to regulate the amount of current flowing through a circuit, or to switch on and off devices in a circuit.The 91A2A-B28-B18/B18L works by changing the resistance in a circuit. When the wafer is turned, it changes the position of the resistance element. This changes the total resistance of the circuit, which in turn affects the current or voltage of the output. The 91A2A-B28-B18/B18L can be used to adjust the output voltage or current from low to high, or from high to low, depending on how the wafer is turned.The 91A2A-B28-B18/B18L can also be used to switch on and off certain circuits. When the wafer is moved to the right, it increases the resistance in the circuit, which effectively cuts off the power to the load device. When the wafer is moved to the left, it decreases the resistance, allowing the power to flow to the load device.Rotary potentiometers, such as the 91A2A-B28-B18/B18L, are useful for applications such as controlling the speed of motors, the brightness of lights, and the audio volume of a speaker. They are also commonly used in radio and audio systems. Rheostats, such as the 91A2A-B28-B18/B18L, are usually employed to control the power supplied to a device, or to switch a load device on and off.In conclusion, the 91A2A-B28-B18/B18L is a high power, low resistance rotary potentiometer-rheostat, designed for switching and adjusting circuits. It is used to adjust the output of a circuit, reduce its power consumption, or switch certain circuits on and off. It can be used in many applications such as motor speed control, light dimming, and audio volume control.
