In this interactive object, learners follow six steps for analyzing a process in a manufacturing setting. This activity includes a drag-and-drop exercise and textboxes where learners post their ideas.

This project gives a drawing with steps to complete the activity.

Learners observe the waveforms in a circuit in which a triac controls the brightness of a lamp’s light. A brief quiz completes the activity.

In this interactive object, learners solve for total resistance and current, the current through each resistor, the voltage across each resistor, and the power dissipated by each resistor.

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.

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

In this animated object, learners examine the operation of a multiplexer and the function of the data input and selector lines. A brief quiz completes the activity.

In this animated object, learners examine the operation of a demultiplexer along with the data output and select lines. A brief quiz completes the activity.

In this animated activity, the learner examines how a 74150 IC multiplexer and a 74154 IC demultiplexer work together when their data select lines are connected to the same input devices.
