Automotive Electrical Systems: VAT-40 Starting System Test
In this highly interactive and animated object, learners examine the VAT-40 battery starting and charging system tester and study how the tester is used to diagnose vehicle starting system problems. This object has audio.
Learners read an explanation of how the Magnetron Ignition System uses a solid state switching component, a step-up transformer, and magnetism to provide a high voltage spark in a one-cylinder combustion engine.
Learners take a close look at the Edison Wire System and observe how the current values through the two lines and the neutral of the system change as the loads vary.
Learners read a description of the wiring configuration of a residential Edison Wire System, which consists of a transformer secondary circuit. The circuit supplies two 115-volt sources and one 230-volt source.
Students read about the Federal Reserve System's structure and goals and the tools it uses to control the flow of money and credit in the economy. At the end of this activity, learners are asked to write how they would solve specific economic problems if they served on the Fed's Board of Governors.
Learners view the waveforms and voltages of an Edison Three-Wire System and read a description of the polarities across the secondary of the center-tap transformer. This transformer supplies power to residential homes.
In this animated activity, learners observe how pressure values throughout a hydraulic system are developed based on pump pressure and the size of the load.
In this interactive object, learners examine how work is performed in foot-pounds by a hydraulic system that uses a pump and cylinder. A brief quiz completes the activity.
In this animated object, learners examine the operation of a feed-forward control system and its advantages over a closed-loop system. A brief quiz completes the activity.
In this interactive object, learners read the definitions of prefixes and suffixes that relate to the digestive system. They then use this knowledge to combine word components to form medical terms.
