Abstract: In this activity, students are led through a series of readings and short experiments to eventually be given a task to determine the relationship between Voltage, Resistance, and Amperage. In the end they are asked to design their own experiment to determine this relationship given several different voltage sources and a constant resistance. By numerical and graphic analysis, students derive Ohms law and test their derivation on a resistor of unknown resistance.
