This type of rheostat is typically referred to as a variable resistor or a potentiometer. It is used to adjust the amount of current flowing through a circuit.
A rheostat works by varying the resistance in a circuit, which in turn affects the amount of current that can pass through. This is typically achieved by adjusting a movable contact along a resistive material, such as a coil or a strip of carbon.
The purpose of a rheostat is to control the amount of current in a circuit. This can be useful for dimming lights, adjusting the speed of a motor, or regulating the temperature in a heating element.
While they may not be as commonly used as they once were, rheostats are still used in a variety of applications, particularly in circuits that require precise control of current. They have also been largely replaced by newer technologies such as transistors and digital potentiometers.
The right rheostat for a circuit will depend on factors such as the desired resistance range, maximum power rating, and physical size. It is important to carefully consider these factors and consult with an electrical engineer or manufacturer when selecting a rheostat for a specific application.
