Learners consider the correct type of pushbutton to use as a Stop button, the way the Stop button should be hard wired, and the PLC input instruction to use. This animated object includes a short quiz. It is recommended that learners review the learning object “The PLC Examine-Off Instruction” before beginning this object.

In this animated and interactive object, learners examine the basic parts and the linear movement of a hydraulic cylinder. A brief quiz completes the activity.

In this interactive and animated object, learners examine orthographic projection and the Glass Box Theory. Front, side, and top view development is demonstrated with pictorial views of each object to help develop 2D to 3D visualization skills.

Students view several examples of how to determine the total impedance of a series circuit. The "j" term is used in all of the calculations.

Learners alter circuit variables and view how these changes affect circuit voltage, current, reactance, impedance, and phase angle.

In this interactive object, learners examine the physical facets that determine the value of a capacitor. A brief quiz completes the activity.

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

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.

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.

This puzzle reviews the parts of scientific inquiry.
