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 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.
This animated lesson shows how a ladder circuit causes the cylinder of a hydraulic circuit to continuously extend and retract after a Start button has been pressed.
Learners complete two exercises. In the first quiz, they divide viruses into two categories: RNA and DNA. They later match each virus with the disease it causes.
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.
Learners read an explanation of variation and how it can make a process unpredictable. They distinguish between common and special causes of variation in a brief exercise at the end of the lesson.
Causes and Risk Factors of Cerebral Vascular Accidents
In this interactive object, the learner examines the causes, symptoms, and risk factors associated with a stroke. The terms "thrombus," "emboli," and "hemorrhage" are defined. A self-assessment of risk factors completes the activity.
In this animated object, learners observe the changes inside the DC shunt motor that could cause the motor to break apart when its field coil opens. A short quiz completes the activity.
In this animated activity, users examine the causes of malfunctions in a hydraulic pressure-reducing valve and the problems that result. A short quiz completes the learning object.
This animated lesson shows how a photoelectric sensor, connected to a ladder circuit, causes the cylinder of a hydraulic circuit to extend and retract.
