Dental x-rays are generated in the dental x-ray tube. Through this animated learning object, students will learn the steps in x-ray generation from turning on the x-ray unit to exposing the dental x-ray film.
Students read an explanation of the use of questionnaires in research. Open-ended and closed-ended questions are defined. Students complete the activity by generating a questionnaire.
General Shop Safety - Hazardous Materials Safety (SDS)
In this learning activity you'll review the hazardous materials safety document which display an example of a SDS or MSDS (Material Safety Data Sheet).
In this animated activity, learners examine how a voltage is induced into a conductor when the conductor cuts across magnetic flux lines. They also view the four factors that determine how much voltage is generated. A brief quiz completes the learning object.
In this 3D animated object, learners examine the way in which a three-phase generator produces three sine waves with three armature coils. A quiz completes the activity.
Learners study the factors that determine the frequency of an AC generator, such as the rotational speed of the armature or the number of stator poles.
This learning object describes the production of an alternating current in a generator with a single-loop armature. An illustration of how a sine wave is produced is shown through animation.
Writers block happens to all of us. Homework block is even worse. If you’re stuck on how to get started, watch this video to explore how to generate ideas for speeches, papers, and projects quickly and effectively.
Automotive Electrical Systems VAT-40 - Generator, Regulator, Diode Test
In this interactive and animated object, learners examine the SUN VAT-40 battery starting and charging system tester. This learning object demonstrates the use of the tester in diagnosing conventional 12-volt automotive charging systems. It contains audio.
