Ohm's Law: Voltage-Current-Resistance Relationship

The Ohm's Law Concept Builder is a tool that allows the learner to predict the effect of varying voltage and varying resistance upon the current in a circuit. There are 12 different situations to analyze and three ability levels. Each situation requires that the learner use proportional reasoning and the I = ∆V/R equation in order to determine the current that results when the voltage and/or the resistance of a circuit is altered. Question-specific help is provided for each of the 12 situations. Use of this Concept Builder with our Task Tracker system allows teachers to track student progress.
