A rotary potentiometer, or rheostat, is a type of electronic component used to control the flow of electricity or other types of energy. It consists of a small knob, or a “dial”, which can be rotated to adjust the amount of energy passing through the device. Rheostats can be used as voltage dividers, used to regulate the voltage applied to a circuit, or as adjustable resistors, used to regulate the current flow in a circuit. The application field and working principle of a 381L100 rheostat will be discussed in this paper. The 381L100 rheostat is a rotary potentiometer with a power rating of 1W. It has an adjustable resistance range of 5 – 5K Ohms, and a tolerance of plus or minus 10%. It is rated for a working voltage of up to 250V, at a temperature of up to 80°C.The 381L100 rheostat is suitable for use in timing circuits, level indicators, voltage control circuits, and other electronic devices. The working principle of the 381L100 rheostat is fairly simple. The rotary knob is connected to an adjustable resistor, which in turn is connected to a circuit. As the knob is rotated, the resistance of the adjustable resistor is changed, varying the amount of energy flowing through the circuit. When the knob is set to a certain position, the amount of energy flowing through the circuit is fixed, allowing the user to adjust the flow of energy to the desired level.The 381L100 rheostat is a reliable and robust electronic component, and can be used in a wide variety of applications. It is commonly used in industrial and commercial applications, such as in HVAC systems, motor control systems, and voltage control systems. The 381L100 rheostat can also be used in domestic applications, such as controlling the dimming of lights or the speed of fans. In conclusion, the 381L100 rheostat is an effective and reliable electronic component, which can be used to adjust the flow of energy in a wide variety of circuits. Its adjustable resistance range allows it to be used in a variety of applications, from commercial and industrial applications, to domestic uses.
