In this interactive object, learners work 10 problems covering resistors, voltage, and current.

In this animated object, learners examine an analog closed-loop feedback system that uses potentiometers to control the position of a gear rack.

The operation and characteristics of an absolute optical encoder used in automation applications are presented.

In this animated and interactive object, learners study the synchronous rotational speed of the magnetic field created by the stator of an AC Motor.

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.
