In this animated activity, learners see that changing the resistance value of the load in the secondary of a transformer causes current to vary in the primary.

In this animated learning object, students read about the operation of a half-wave rectifier.

Students work practice problems in which the total resistance of the circuit is calculated. Feedback is provided.

This interactive learning object demonstrates how the moisture content is determined for a given sample of soil or aggregate.

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 learning activity you'll create a packet filter.

In this learning activity you'll examine how a large computer network is configured.
