The potentiometer essentially functions as a variable voltage divider. The position of the wiper determines the output voltage of the potentiometer.

This versions of potentiometer uses a rotary motion to move the slider around a track that compromises most of a circle with contacts at either end of the track in the area where part of the circle is missing.

Potentiometer resistor function. A resistor of which the ohmic resistance value can be adjusted. Types of variable resistors potentiometer. In a circuit where they are used strictly as variable resistors or rheostats only two terminals are wired to the other components.

The most common of variable resistor or potentiometer is a rotary version. It functions as a potential divider and is used to generate a voltage signal depending on the. Today potentiometers are much smaller and much more accurate than those early large and bulky variable resistances and as with most electronic components there are many different types and names ranging from variable resistor preset trimmer rheostat and of course variable potentiometer.

The symbol for a potentiometer is the same one as a resistor save for an arrow in the middle. Either mechanically potentiometer rheostat or electronically digital potentiometer. Potentiometer does not produce any signal it is merely a variable resistor whereby any signal impressed on it can be variably taken out of the wiper as a linear function or logarithms function.

All three terminals are wired separately when they function as voltage dividers. The potentiometer is the most common variable resistor. 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.
