Description:

A potentiometer is a manually adjustable variable resistor with 3 terminals. Two terminals are connected to both ends of a resistive element, and the third terminal connects to a sliding contact, called a wiper, moving over the resistive element. The position of the wiper determines the output voltage of the potentiometer. The potentiometer essentially functions as a variable voltage divider. The resistive element can be seen as two resistors in series(potentiometer resistance), where the wiper position determines the resistance ratio of the first resistor to the second resistor.

Features:

• Carbon resistive element

• Dust proof enclosure

• Heat-resistant material

• Low cost

• Long life models (10000 cycles)

• Simple construction

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.

Application:

Ideal for various TV and audio products and general purpose as well.

How does a potentiometer work?

It has three terminals.

The terminal at each end is internally connected to a resistor of fixed value in Ohms. The center terminal is internally connected to a wiper that touches the resistor and can be moved along its length.
