Open in the lab Embed The simulation runs as a demo that pauses after two minutes; open it in the lab to keep going.

How it works

Resistance on the Variable Resistor(Potentiometer) is set to 530 Ohms.

Click on the potentiometer and open up the settings.

At the bottom of the popup window you can adjust the resistance.

* Notice when the resistance "wipe" switch is set to the middle, the current running on each side of the circuit is about the same.

*Notice when you slide the wipe switch to either Left or Right, the current will increase and decrease proportionately

**NOTE: you can also adjust the resistor wheel with your cursor, but it is not as easy to adjust
