Intro
Transformers and coils are basic components used in practically all electronic apparatus. A knowledge of their characteristics and behavior is therefore a prerequisite to a clear understanding of electronic circuitry. Although there is nothing mysterious about the electrical behavior of transformers and coils, there are many incorrect notions about them, even among experienced technicians.
The purpose of this guide is to present the basic concepts in terms that even the beginning student of electronics can easily comprehend. Important mathematical relationships and formulas are presented in the text, but not as a substitute for adequate verbal explanation.
This revised edition of "Understanding Transformers and Coils" has been updated to reflect new developments in core materials and manufacturing techniques. It also contains new sections on toroidal and ferrite-bead inductors, and an added Section on magnetic core memory and logic.
The author expresses acknowledgement and gratitude to the many manufacturers who supplied illustrative material for this guide.
