Description:
A potentiometer can refer to two types of devices: an instrument used to measure electromotive force, or an electronic component with an adjustable resistance. In the latter case, a potentiometer is generally a resistor with a sliding contact that is mounted on a rotating shaft. This device serves as a voltage divider that allows the user to alter the level of resistance offered to the current flowing through it, which means that the output voltage can be modified to anywhere between the maximum level of incoming current and zero volts.
Carbon Potentiometer is an electronic component classified as variable resistor. Carbon Potentiometer is used as voltage divider to provide variable output voltage. Carbon Potentiometers uses carbon as resistive element. There are also different types of Potentiometers like Wire Wound type and ceramic type using different materials on resistive element. Carbon Potentiometer can be classified into logarithmic type and linear type depending on the mode of operations. Carbon Potentiometers are of many types and sizes depending on resistance value, power rating and type of mounting.
Panel mounted type Carbon Potentiometer are widely used for volume and tone control in consumer and entertainment electronics. PCB mount type is used as function controller, measuring and testing equipment, medical electronics, industrial electronics etc. Carbon Potentiometer is available with and without switches. There are also many varieties of spindles used for carbon potentiometer depending on the materials and sizes.
