The two types of digital devices, logic gates and flip-flops, and the types of basic operations they perform are presented.

In this document you'll review drill press work-holding devices.

Instructions on how to use and construct a truth table for digital devices are provided.

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.

Learners follow a step-by-step explanation of how to test fuses and circuit interrupting devices.

This project gives steps to complete the activity.

In this animated object, learners examine the fundamental operation of a diac including how it is turned on and turned off. A brief quiz completes the activity.

In this learning activity you'll describe the operation of a logic inverter using a truth table, a Boolean Algebra equation, a switch analogy, and a written statement.

Learners study the fundamental operation of a triac, particularly how it is turned on and off. A brief quiz completes the activity.

Learners use the National Electrical Code to determine the size of a motor overload protection device.
