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

Students examine the full-wave rectifier. They review appropriate formulas and examples of actual circuits.

In this animated and interactive object, learners calculate the area and centroid of a circle.

Learners read how the RL high pass filter is developed. The transfer function is used in Excel to graph the Vout. The circuit is also simulated in Electronic WorkBench and the resulting Bode plot is compared to the graph from Excel.

In this learning activity you'll explore how units in the metric system are related to each other and practice locating measurements on a metric line.

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.

In this animated object, students view an explanation of how current, voltage, and the charge on a capacitor of a series RC circuit change during five time constants. A short quiz completes the activity.

In this animated object, learners examine how current, voltage and the discharging capacitor of a series RC changes during 5 time constants. A brief quiz completes the activity.

In this animated learning object, students examine current, voltage, and the magnetic field strength of a series RL circuit while it is de-energizing during five time constants. A quiz completes the activity.
