In this animated activity, learners examine how various NAND gate configurations and the logic signals produced throughout the circuit perform the functions of all of the other types of logic gates.

Learners examine the internal parts of a DC electrical motor and then text their knowledge in a drag-and-drop exercise.

In this learning activity you'll determine the voltages that can be topped off of a multi-resistor voltage divider that has one main power source.

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

In this learning activity you'll create a packet filter.

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.

Students read about the ideal versions of the four common filters (low-pass, high-pass, bandpass, and notch), and view graphical representations of the filters' frequency characteristics.

In this animated lesson, learners follow the steps required to read the phase shift difference in degrees between two AC waveforms.

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.
