In this learning activity you'll review the process of solving for the total resistance in a series DC circuit.

Learners study animated rheostat settings that show how varying the current flow affects the amount of power that is dissipated in a series circuit. Nine review questions complete the activity.

In this animated object, learners examine the operation of up-counters and down-counters for a programmable controller. A brief quiz completes the activity.

Learners study the types of information letters and numbers placed inside general piping and instrumentation diagram symbols.

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.

Learners read a description of torque and study the factors that cause its magnitude to change. A brief quiz completes the activity.
