Learners test their knowledge of the variations of Watt's Law and Ohm's Law with this quiz.

This interactive object is designed to help learners memorize schematic symbols used in pneumatic diagrams. Learners quiz themselves using electronic flashcards.

Learners examine how to convert numbers from rectangular to polar form and from polar to rectangular form using a TI-83 Plus calculator.

Learners examine the basic types of dimensioning including unidirectional and aligned systems, and linear, aligned, angled, arrowless, chain, datum, chart, tabular, radius, diameter, typical, and reference dimensions.

In this animated object, learners examine the operation of a zener diode in the forward and reverse bias conditions. A quiz completes the activity.

Learners view the operation of a full-wave rectifier which has two diodes.

Learners see how a bridge rectifier converts an AC voltage into a pulsating DC voltage. A brief quiz completes the activity.

In this animated learning object, students read about the operation of a half-wave rectifier.

In this animated object, students observe how the pulsating DC output voltage of a full-wave rectifier is filtered by a capacitor.
