In this interactive object, learners solve a series-parallel DC circuit analysis problem. Immediate step-by-step feedback is given.

In this animated object, learners examine the concept of gear ratios. The number of teeth, diameters, and velocity relationships are discussed and calculated using linear ratio equations. A quiz completes the activity.

In this animated object, learners examine the factors that determine how well a capacitive proximity sensor can detect an object. Those factors include size, position, and the materials from which the target is made. A brief quiz completes the activity.

In this interactive object, learners determine the pulse width, period, duty cycle, and frequency of a waveform.
