Potentiometer are very important part of electronic circuits as they are used across wide range of applications ranging from comparator circuits, voltage control, LED intensity to even volume and fan speed control in our homes. A potentiometer is a variable resistor with three terminals, where Two terminals are connected to a resistive element and the third terminal is connected to an adjustable round wiper. The position of the wiper determines the output voltage.
Potentiometers are variable resistances as they can provide a variable resistance by simply varying the knob on the top. The resistance value at the output pin will decide the amount of resistance offered to the current flow and hence by varying the resistance we can control the current flow in the circuit. This 500 ohm compact linear Potentiometer with plastic dust-cap is suitable for bread board as well as PCB. This is center tap type so two pins will measure full 500 ohm resistance and on third pin resistance will vary in accordance to rotation. A small flat screw driver is used for changing the value. They are not meant to be used by end used but in final assembly line to set sensitivity and calibrate the circuits, that is why they have low rotation life.
