Series and parallel circuits the easy way, and bundled to boot!
We want our students to build circuits to understand Ohm's law, potential difference, current, and resistance, but most of the lab time is spent fighting with the equipment. Loose wires, worn out batteries, dead light bulbs and miss-wired ammeters mean that students don't really get the point of what they are doing. Phet simulations allow students to build series, parallel, and complex circuits and focus on the concepts and the m
