Description

Look inside a battery to see how it works. Select the battery voltage and little stick figures move charges from one end of the battery to the other. A voltmeter tells you the resulting battery voltage.

Sample Learning Goals

  • Do the small blue spheres represent positive or negative charges?
  • Which side of the batterey is labeled positive, and which side is negative?
  • How can you determine which side of the battery is positive and negative just by the location of the blue charges?
