In this animated and interactive object, learners examine a depiction of how force is multiplied by a larger cylinder when pressure from a pump is applied to a smaller cylinder. A short quiz completes the activity.

Students read about light-emitting diodes, including LED voltage and current, and how to protect against reverse voltage.

Learners view the steps for testing a capacitor with an analog ohmmeter. A brief quiz completes the object.

Learners examine the basic elements of a machine vision system. A short quiz completes the activity.

This activity is a simulation that allows the learner to practice personal protective equipment tasks.

In this simulation activity, an electrician will troubleshoot an AC motor that is overheating. Before accessing blueprints and then using a multimeter to find the fault, the learner will follow safety protocols by following lock-out tag-out procedures and then suit up with appropriate (PPE) personal protection equipment.

In this simulation activity, an electrician troubleshoots a defective compressor motor that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.

In this simulation activity, an electrician troubleshoots a defective water pump that will not start. To find the problem, the learner selects the appropriate blueprints that must be referred to while performing the troubleshooting steps. Then safety protocols will be followed, such as making lockout-tag out installations and donning PPE items before taking measurements with a multimeter to locate the faulty component.

In this animated object, students view an example of how to convert rotational velocity to linear velocity. They then work practice problems.
