The potentiometer can work as a rheostat (variable resistor) or as a voltage divider.. Rheostat. To use the potentiometer as a rheostat, only two pins are used: one outside pin and the center pin. The position of the wiper determines how much resistance the potentiometer is imposing to the circuit, as the figure demonstrates:

Potentiometers work by having a resistive element inside. Both end terminals are attached to it, and do not move. The wiper travels along the strip when the knob is turned. The closer the wiper is to the end terminal it is wired in conjunction with, the less the resistance, because the path of the current will be shorter. The further away it ...

A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. If only two terminals are used, one end and the wiper, it acts as a variable resistor or rheostat.. The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential (voltage); the component is an implementation of the ...

How does a potentiometer work? Ask Question 0 \\$\begingroup\\$ A lot of places where I've read explanations about potentiometers either go into so much detail or they're so superficial that I don't understand the actual concept behind it. How would you easily explain to me what a potentiometer is and how it works?

In this blog post I'll start experiencing with potentiometers and how to use them with Arduino. Voltage divider circuits There are situations in which one part of a circuit only needs a percentage of the available current. An example I already experienced is using an LED in series with a resistor.
