In this animated object, learners examine the operation of a capacitive proximity sensor. A brief quiz completes the activity.

In this animated object, learners examine how the rotation of an induction AC motor's armature slips behind the synchronous rotational speed of the stator's field to create magnetic fields. These fields interact and produce torque. A quiz completes the activity.

Students examine how to interpret resistor color code bands to determine resistance values and tolerance ranges. This interactive learning object has audio content and includes exercises.

In this animated lesson, learners examine the rectifier circuitry in a DC variable speed drive that supplies the voltages to the field coil and armature.

In this animated lesson, learners examine sine waves and alternating current. A brief quiz completes the object.

In this animated object, learners examine cycles, frequency, Hertz, wavelengths, and periods. A brief quiz completes the activity.

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 and animated object, learners examine the flow of electron current into and out of hot and neutral sockets during each alternation of an AC waveform. A brief quiz completes the activity.
