In this interactive simulation adapted from the University of Colorado's Physics Education Technology project, learn about the relationship between electric current, voltage, and resistance. Known as Ohm's law, this relationship can be described by the equation V = I x R. In this activity, you can adjust the voltage and resistance in a simple circuit to see how the current changes according to Ohm's law.

This media asset was adapted from Ohm's Law by PhET.
