This is an original PowerPoint animation that demonstrates the different between a series circuit and a parallel circuit. It shows both the standard circuit symbols, as well as pictures, complete with batteries, light bulbs, and wires. The animation shows what happens when a bulb is removed from each circuit, demonstrating that a complete loop (circuit) is necessary in order for current to flow. The slides can be modified if the user wishes to add more bulbs, etc. Thanks! Michael Guarraia
