Students read about the four steps to creating an ac model and view examples.

Students calculate current, phase angle, resistor voltage, inductor voltage, and power.

In this interactive object, learners examine how hydraulic oil is contaminated, the types of damage contamination can cause, and the methods used to clean the oil.

In this simulation, learners follow steps to clear out a job that had been previously created.

In this learning activity you'll create a stem and leaf plot.

In this animated activity, learners study how stator poles create a rotating field in a three-phase AC motor as a three-phase AC voltage is applied.

In this animated object, learners study the drawbacks of a single-loop armature of a DC motor and the advantages of a multi-loop armature.

In this animated activity, learners study how the magnetic field of an armature can distort the DC motor's main magnetic field. A brief quiz completes the object.

In this animated object, learners study the rotation of the magnetic stator field of an AC motor and how it interacts with the armature to cause rotation. A short quiz completes the activity.
