In this animated object, learners observe the voltage on a capacitor at various time constants when it either charges or discharges. Students then answer questions in the categories of Identify, Compare, and Compute.

Use Ohm's law, Watt's law, and the power equation to derive formulas for the DC power wheel.

This animated lesson shows the operation and characteristics of thru-beam optical sensors.

Students read descriptions of the voltage, current, and turns ratios of the primary and secondary coils for a transformer in this interactive lesson.

In this interactive and animated object, learners practice testing a diode. They determine if a diode is good, open, or shorted.

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

This learning object introduces the three approximations of a diode.

Students read how to set up the optical comparator edge detector in this interactive learning object.

The learner tests his/her ability to set up the optical comparator edge detector using a virtual simulation of the machine.
