Rent 9781401835927 | CD-ROM #1 for Herman's Residential Construction Academy: Electrical Principles

Summary Table of Contents

A companion to the RCA Electrical Principles text, the RCA Electrical Principles Video Series introduces the viewer to electrical theory and its applications through an overview of important concepts, equations, and practical examples. The series contains a set of eight, 20-minute videos, covering direct and alternating current, as well as an introduction to Single Phase Motors. Full-color graphics and animations illustrate important concepts, creating a visually appealing presentation that is easy to follow and understand. Create a direct link between your education/training program and the residential construction industry! Training materials are now available for many of the residential crafts based on skill standards developed by the nation�s leading builders and educators. The result of a strategic partnership between the National Association of Home Builder�s Home Builders Institute and Delmar Learning, the Residential Construction Academy Series is the perfect way to teach essential workplace skills to people new to the building trades. Ideal for use in vocational programs, workforce development programs, professional associations, and trade unions, all materials are based on industry standards. The Residential Construction Academy also offers credentialing for programs using the skill standards and materials, along with a national registry of students who have successfully completed participating programs. The goal is a workforce that is skilled, knowledgeable, and able to meet the needs of the industry today and well into the future.
