For nearly half a century, Direct Current Fundamentals, a widely acclaimed publication, has presented the fundamentals of direct current electricity and magnetism in a straightforward, practical manner. The 7th Edition retains the distinguishing features that are the cornerstone of this winning book, including logically organized content that progresses from basic principles to more complex concepts. Enhancements include updated drawings and photographs that better assist you in understanding such essential concepts as how to distinguish between digital and analog meters, and solid state control for direct current motors.
Features:
- Units related to numerical concepts, electrical measurements, and scientific notation have been augmented during the revision process for an enhanced learning experience.
- New formulas for voltage dividers and current dividers have been added, along with step-by-step instructions on how they can be applied to a circuit.
- A chapter on solving direct current networks includes easy-to-understand solutions of the loop current method, superposition technique, Thevenin's Theorem and Norton's Theorem.
- Achievement reviews at the end of each chapter offer a variety of practice problems, all of which have been field tested.
- While direct current concepts are conveyed in a practical, non-mathematical fashion, important math concepts are explained step-by-step when necessary.
From the Preface:
Direct Current Fundamentals is a revised edition of a widely acclaimed textbook that, for nearly half a century, has helped thousands of students launch their careers in electricity and electronics.
Like its predecessors, this seventh edition is designed to help the beginning student at community colleges, vocational schools, technical institutes, and high schools learn the fundamental concepts of DC electricity and magnetism. No prior knowledge of electricity is assumed, but the basic skills of algebra are required. Although knowledge of basic algebra is required, this text does not present electrical concepts from a mathematical standpoint, but in a straightforward practical manner.
Throughout the revision process, attempts have been made to improve perceived shortcomings without disturbing the specific features for which countless instructors have praised Direct Current Fundamentals, 7th Edition.
Additional Features:
- Every chapter is introduced with a set of learning objectives.
- Every chapter identifies new vocabulary and technical terms.
- Text material is organized in short sections that are limited to a specific topic and identified by number and subtitle.
- Whenever possible, illustrations have been placed in close proximity with the appropriate explanation.
- Every chapter is summarized in a series of brief, concise statements.
- The achievement reviews at the end of each chapter offers a variety of practice problems, all of which have been field tested.
- The instructor's guide, available from the publisher, has been revised to contain additions to new and updated information.
- A list of basic electrical symbols is found in the Appendix.
- A glossary is included.
- Certain topics have been expanded, including units related to numerical concepts, electrical measurements, and scientific notation.
- Different types of circuits are grouped under their respective individual chapters.
- New formulas for voltage dividers and current dividers have been added, along with step-by-step instructions on how they can be applied to a circuit.
- A new chapter has been added on solid-state control of DC motors.
- Chapter 24, Solving DC Networks, includes detailed solutions of the loop current method, superposition technique, Thevenin's theorem, and Norton's theorem.
In Direct Current Fundamentals, 7th Edition, topics dealing with electrical measurements have been revised and augmented with new materials to help explain how digital meters differ from analog meters. Many of the illustrations have been revised to better convey the concepts they are intended to help explain.
