Considering this, how does the potentiometer work?

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 symbol for a potentiometer is the same one as a resistor, save for an arrow in the middle.

Similarly, why do potentiometers have 3 pins? A 3 terminal pot used with 3 terminals, is basically just a voltage divider. As you move the wiper, you increase one resistor in the voltage divider, while decreasing the resistance in the other. So long as the wiper is connected to one leg of the potentiometer, it will behave a variable resistor.

Also to know is, what are the 3 terminals on a potentiometer?

A potentiometer has 3 pins. Two terminals (the blue and green) are connected to a resistive element and the third terminal (the black one) is connected to an adjustable wiper. The potentiometer can work as a rheostat (variable resistor) or as a voltage divider.

Does a potentiometer change voltage?

Potentiometers, trimmers, and rheostats are all variable resistors. Potentiometers and trimmers are used to create a variable voltage by varying the voltage between their wiper terminal and two ends. Rheostats are used to vary the amount of current.
