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.
Material condition modifiers may be applied to tolerances for geometric characteristics of features of size. A feature of size is one that can be measured across two opposing points, either internally or externally.
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.
Learners examine the wiring of the primary components of the three types of DC motors, series, shunt, and compound. The operational characteristics of each type of motor are described. A quiz completes the activity.
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.
In this interactive object, learners read the characteristics of each stage of labor and delivery. They then identify the stages in a multiple-choice assessment.
