A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. Here is the circuit diagram of a simple potentiometer:
```
_________
| |
A--| |-----B
| POT |
C--| |
|_________|
```
In the circuit diagram above:
- Terminal A is connected to the input voltage (V_in).
- Terminal B is connected to the output voltage (V_out).
- Terminal C is connected to ground.
- The sliding contact of the potentiometer is used to adjust the output voltage by changing the resistance between terminals A and B.
