In this animated and interactive object, learners study the synchronous rotational speed of the magnetic field created by the stator of an AC Motor.

Learners review the three formulas for power and work 12 problems. In each of the problems, students are given two of the three variables (voltage, resistance, or current) and asked to solve for power. Immediate feedback is provided.

Students view the mathematical expression of an AC waveform with respect to time (t) and read about the different components of this expression.

In this animated activity, learners view how to clear and preset a flip-flop to store a logic 0 or a logic 1.

Learners answer questions about nonferrous metals and alloys using a game show format. Immediate feedback is provided.

Learners read about the six levels of the psychomotor domain taxonomy and quiz themselves on a basic understanding of the content.

In this interactive object, learners assign water supply fixture units to a water distribution system using Section 82.40 of the Wisconsin Plumbing Code.

Learners follow steps to size a sanitary sump using the Wisconsin Plumbing Code. A quiz completes the activity.

In this animated object, learners see how a time proportioning operational amplifier varies an average DC voltage. A brief quiz completes the activity.
