In this animated and interactive object, learners follow three steps to calibrate an opposed optical sensor. They consider horizontal alignment, the sensitivity setting, and having an effective beam.

In this animated object, learners examine the proper way to reset a counter instruction in a programmable controller.

In this animated object, learners examine how a Hall-effect sensor operates. A short quiz completes the activity.

Students read how to determine and calculate the saturated unit weight for a given sample of soil or aggregate, based on the weight-volume relationship. Practice problems complete the activity.

Students solve problems on the determination of total inductive reactance of series-parallel inductors.

Students solve problems on the determination of total capacitive reactance of series-parallel capacitors.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a series RLC circuit when the applied frequency is increased from 0 Hz towards resonance.

By playing a game of tic-tac-toe, a student can review what happens to currents and voltages throughout a series RLC circuit when the applied frequency is increased above resonance.

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.
