Rotary Potentiometers, Rheostats

A rotary potentiometer is a device that many engineers use as a variable resistor. It is a three-terminal passive component that is used to measure changes in resistance and can be used to control the voltage or current in an electrical system. A rheostat is a potentiometer that is specifically designed for controlling larger amounts of current. It consists of two terminals, which can be connected with a wire or another metal rod. This type of potentiometer is particularly useful for controlling electrical loads that require high current, such as motors or light bulbs. The most notable use of rotary potentiometers is for controlling the amplitude of signals in audio and video equipment. By changing the resistance of the potentiometer, the user is able to adjust the volume of music or change the contrast level of a television. Rotary potentiometers can also be used to regulate the flow of fuel in a carburetor. By adjusting the amount of fuel entering the combustion chamber, the air-to-fuel ratio can be precisely controlled. Additionally, they can be used in motor speed control circuits for controlling the speed of a motor without the need for external voltage or current sources. Rotary potentiometers are also used in pressure transducers for measuring pressure levels. As the resistance of the potentiometer changes with the pressure level, the voltage across the device can be used to calculate the pressure at any given moment. Rotary potentiometers are typically constructed from three sections: A terminal on either side of the resistive element, a central lug, and a wiper that slides over the central lug. As the wiper is moved over the resistive element, the total resistance changes. This change in resistance is dependent on the thickness of the resistive element and on the number of turns in the resistor. Rheostats are usually composed of one or two adjustable arms, a resistive element, and two leads. One lead is connected to a fixed terminal, and the other is connected to the resistive element. As the arm is adjusted, the resistance between the two terminals is changed. This type of potentiometer is very useful for controlling the current in electrical devices such as motors, lights, and pumps. The working principle of both rotary potentiometers and rheostats is based on the resistance that occurs when a current passes through a conductor. By changing the resistive material, the resistance of the potentiometer can be controlled. The resulting change in resistance is what allows users to control the voltage or current in their system.
