This page contains a simple Java applet that gives users a look inside a battery to see how it works. It features a cross-sectional battery filled with blue spheres representing charges. As users change the voltage, little stick figures move the blue charges from one end of the battery to the other. A voltmeter displays the resulting battery voltage. Students must determine which side of the battery is positive or negative from the information at hand.
