This animated lesson shows how pushing a start or stop button on a ladder circuit causes the cylinder of a hydraulic circuit to extend and retract.

Learners compare the experience of driving an auto to the circuit responses of RL (resistance/inductance) circuits and RC (resistance/capacitance) circuits. Acceleration, position, speed, and torque are graphed.

Students read about the concepts of saturation and cutoff. They view diagrams that illustrate the interaction of the load line and the family of curves.

Learners examine the operation of a proportional control amplifier and the two ways that it is programmed using proportional gain or proportional band. A brief quiz completes the activity.

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.
