Circuit Simulator

Circuit Simulator is built using HTML5 and will run in any modern browser on a reasonable fast machine. You can hook up all the usual components of a circuit including resisters, capacitors, voltage sources, wires etc. and visualize how it works without building anything physical. A great way to experiment!
