This applet models the relationships among voltage, resistance, and current in a branched circuit. Each of the values is updated when changes are made in the circuit's voltage, current, or resistance.
Clicking on E+ increases the electromotive force (voltage), and clicking on E- decreases the voltage. Clicking on I+ increases the current, and I- decreases it. Clicking on R+ increases the resistance, and clicking R- decreases it.
