Students view drawings of the dc analysis of a voltage-divider biased NPN transistor.

Students work nine practice problems to determine total series inductance. Immediate feedback is given.

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.

In this learning object you'll explore some frequently asked questions concerning steel rule usage.

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.
