Students answer 10 questions in a sample exam. This exercise covers number systems, number conversion, logic gates, and combinational design. Feedback is provided.
Learners read an explanation of the concept of apparent power in a power distribution system involving motors, generators, and transformers. A quiz completes this interactive lesson.
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.
Automotive Electrical Systems: Effects of a Rheostat in a Series Circuit
In this animated object, learners examine how the way in which a rheostat is connected in series with other resistors causes current and voltage to change as the resistance is varied.
Automotive Electrical Systems: Effects of a Rheostat in a Series-Parallel Circuit.
Learners examine the current and voltage changes in a series-parallel circuit as the resistance value of a rheostat is varied. Illustrations and calculations are included.
In this interactive and animated object, learners examine Midtronics hand-held battery and charging system testers and view the operation of these testers in an automotive repair facility.
