Potentiometer

 

1) Variable resistor

2) Wiper moves between two leads. Resistance between wiper and lead determines resistance

3) Resistance between leads is maximum resistance of potentiometer.

4) Comes in dial, slider, and trimpot form

5) With linear pots resistance varies directly with the rotation of the knob.

6) With logarithmic pots resistance varies exponentially with the rotation of the knob.

6) Some other variable resistors include heat sensors, photoresistors and bend sensors.
