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

In this animated and interactive object, learners use rotational input velocity to determine the linear output velocity of a rocker or lever. Learners test their knowledge in an exercise at the end of the activity.

Students view the steps for determining the total capacitance for a series circuit. They then work practice problems.

Students look at the power dissipated by a single gate and by an IC. The concept of average current draw is introduced and examples are provided.

Learners view the operation of the 7485 integrated circuit magnitude comparator in this animated object. A quiz completes the activity.

Students read about the three main classes of amplifiers and view graphical representations of the collector current and circuit.

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

Students read an explanation of the operation of an operational amplifier that functions as a comparator.

In this interactive object, learners examine the operation of an inverting operational amplifier through formulas, tables, and animated illustrations. A brief quiz completes the activity.
