This web page is an interactive physics problem on RC circuits. The user can alter the frequency of the alternating current to observe how this affects the voltage and current. An inductor can be substituted for the capacitor, to view the differences between the two in an AC circuit. The guide on the page explains impedance and how the voltage drop and current can be calculated for each circuit.
This is part of a collection of similar simulation-based student activities for introductory physics.
