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

Learners examine the labeling scheme used in ladder logic diagrams to identify components, wires, rungs, and rails. This activity includes self-check questions.

Students examine AutoCAD toolbars and toolbar commands. They then test their knowledge in a matching exercise.

This learning object shows the symbols used to represent the type of pulse required at the clock input to activate flip-flops.

Learners read a description of how an oscilloscope is used to measure the frequency of a sine wave.

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, learners drag resistors of the proper value into a series circuit to cause a required amount of current to flow. Seven review questions complete the activity.

Learners examine a photo of a Marvel Vertical Band Saw and then identify the parts in a drag and drop exercise.

In this simulation, learners follow a series of steps to operate the Marvel Saw PCII in the manual mode. This activity includes a video clip.
