Examining a potentiometer

Use the multimeter set to resistance to investigate a potentiometer.

Connect the meter across the two outside probes.

Record the reading:

Twist the knob, how does that effect the resistance?

Disconnect the meter and turn the knob so it can't turn any more. Connect across the outside and the middle probe.

Record the reading:

Twist the knob, how does this effect the resistance?

Predict what would be the reading if the meter was connect across the other end and the middle.
