Rotary Potentiometers, Rheostats, are largely used in various application fields, including industrial machinery, home appliances, heating and cooling systems, and auto electronics. The application field of the 381N10K can be divided into two parts, depending on its working principle.

The first application field is as a variable resistor. As a variable resistor, 381N10K can be used to adjust the electrical signal path in many circuits, such as the voltage regulation and impedance matching. The 381N10K is composed of a rotary potentiometer, a rheostat, and a switch. The rotary potentiometer has two elements, a resistive element and a snap switch. The resistance can be adjusted by rotating the switch to vary the voltage or current of the circuit. The second application field is as an on/off switch for control systems. A 381N10K is used to switch the circuit on or off, depending on the position of the dial.

The working principle of the 381N10K is based on the concept of voltage divider. When the movable knob of the rotary potentiometer is rotated, the voltage divided across the resistive element is changed, thus changing the current in the circuit. The current depends on the position of the knob, and the voltage corresponds to the resistance of the resistive element. Additionally, when the dial switch is activated, it changes the resistance value as well as the voltage, thus changing the current again.

The 381N10K is a versatile device with many applications. It can be used as a variable resistor to adjust the current or voltage in a circuit, or as an on/off switch in a control system. It is important to note that the 381N10K can be used in both types of applications, depending on the setting of the dial switch. Its working principle of voltage division makes it suitable for many different types of applications.
