In this animated activity, learners study the principle behind an inductor producing a high momentary voltage while its magnetic field collapses. A short quiz concludes the lesson.

Students read about the edge-finder's parts and assembly, and view video clips of the tool in action.

In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

Learners examine a series-parallel circuit and solve 14 problems related to voltage, current, and power. A help screen is provided.

In this learning activity you'll examine how electronic converters convert between analog voltages and proportional digital signals.

Learners work problems to make conversions between RMS, average, peak, and peak-to-peak AC voltages.
