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

In this animated object, learners examine the formulas used to convert peak, RMS, average, and peak-to-peak AC voltages. A brief quiz completes the activity.

In this interactive exercise, learners review definitions of 26 terms and then test their knowledge in a matching exercise. Only six terms are included in the quiz; however, if the learner clicks “Restart,” more terms appear in random order.

Learners view waveforms at various locations of an SCR circuit controlling the intensity a light bulb. The waveforms are shown when the light is dim, at medium brightness, and at full brightness. A brief quiz completes the activity.

This project gives a drawing with steps to complete the activity.

In this learning activity you'll match definitions of motivational terms with terms and concepts found in a puzzle.
