This page is a simulation-based tutorial on resistance, the property of a substance that impedes the flow of electric current. It contains three interactive simulations: one allows the user to glimpse resistance at the molecular level, the second explores Ohm's Law, and the third introduces the use of color coding in composition resistors. The author uses diagrams to illustrate arrangements of resistors in series and parallel circuits, with explanations of how to calculate equivalent resistances.
