Improving Your Welding Technique
Learners will follow general tips and tricks for improving their basic welding technique.
The Superposition Theorem
By Patrick Hoppe
The superposition theorem is explained as it relates to dc circuit analysis. Examples are given.
Calculating Blank Size for Rolled Sheet Metal (Screencast)
By Dave Hoffman
In this interactive object, students read how to calculate the blank size for cylinders in a three-roll pinch roller. A calculator is required for the brief quiz that completes the activity.
By Terry Bartelt
This learning activity presents information on how the type of material used for the dielectric of a capacitor affects the capacitor's value in farads.
Schematic Diagram Symbols
In this learning activity you'll review various types of common components used in electronics and view their schematic diagram symbols.
Electrical Switches & Pushbuttons
In this learning activity you'll review the operation and schematic symbols of various types of switches and push buttons used for electronic circuits.
Assembling a Circuit from a Schematic Diagram
In this animated object, students examine the steps for wiring an electrical circuit from reading a schematic diagram.
In this learning activity you'll describe the operation of an AND gate by using a truth table, a waveform diagram, a Boolean Algebra equation, a switch analogy, and a written definition.
Logic State Signals
In this learning activity you'll identify the voltage levels produced or recognized by digital logic devices as valid or invalid logic state signals.
Nondestructive Examination Symbols
You'll learn to identify nondestructive examination abbreviations and they use in examination symbols.
You'll focus on terminology related to designing a hypothetical program.
