In this learning activity, you’ll explore the characteristics of common, carbon steel shielded metal arc welding electrodes, which fall under American Welding Society specification A5.1.
Learners use peripheral vascular assessment data to examine characteristics of these four conditions: peripheral arterial disease, deep vein thrombosis, chronic venous insufficiency, and acute arterial occlusion. A matching exercise completes the learning object.
In this interactive object, learners examine the characteristics of effective visual displays. This activity is designed primarily for instructional assistants.
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.
Transistor Fundamentals: Junction Field Effect Transistor (JFET)
Students read about the common characteristics of the Junction Field Effect Transistor. They also explore the schematic symbols and the basic operation of the JFET.
Students read about the ideal versions of the four common filters (low-pass, high-pass, bandpass, and notch), and view graphical representations of the filters' frequency characteristics.
