In this interactive object, learners determine the Vp, Vp-p, Vrms, Vavg, and the frequency of a sine wave that is displayed on an oscilloscope screen.

In this animated lesson, students read an analogy comparing water in a "special" water tank to the current "flow" through a capacitor.

Students complete 10 practice problems. These deal with the determination of series current, zener current, and load current, and if the zener diode is operating in the breakdown region.

This is an animated troubleshooting exercise that takes voltage measurements to determine the fault of three different series circuits. There are six review questions that enable the learner to determine the effectiveness of the troubleshooting presentation.

In this learning activity you'll examine how electronic converters convert between analog voltages and proportional digital signals.

Learners read how an inductor opposes a current change when it begins to energize and when it begins to de-energize. A short quiz completes the activity.

Students solve six problems for series impedance using complex numbers. Immediate feedback is given.

Students work six practice problems to determine the total impedance of a parallel circuit.

Students solve five problems to determine the total impedance of a series-parallel circuit. Immediate feedback is given.
