Learners examine the sourcing and sinking of conventional current at a PLC output module and the type of field device to which it is connected. This interactive learning object includes six quiz questions.
In this animated and interactive object, learners use a memory device to identify NPN and PNP transistors. Learners also examine how much the transistors turn on when the voltage applied to the base is varied.
In this interactive object, learners examine the characteristics of osteoarthritis, rheumatoid arthritis, and osteoporosis. Students then describe the precautions to be aware of when working with clients who have arthritis and identify assistive devices that clients might use to prevent injuries at home.
