Now in its fourth edition, Electronics for Electricians is written for apprentices and readers preparing for work in industrial settings. Components and circuits are explained in a clear-cut manner throughout the book, with emphasis on describing how they work, what they do, how to use them in a working circuit, and how to test them. With successfully proven laboratory experiments in every chapter, this book exposes readers to the electronic devices commonly found in industry as well as the circuit applications of those devices. In the process, it offers its readers a more practical and relevant path to understanding how electronics theory is applied in the electrical field.

This text is written for apprentices and readers preparing for work in industrial settings. Components and circuits are explained throughout, with emphasis on describing how they work, what they do, how to use them in a working circuit, and how to test them. A non-mathematical approach allows for a wide readership. Learning features include chapter review questions and laboratory experiments. Experiments use common components that are inexpensive and easy to get. This fourth edition includes new information on semi-conductor materials, metal oxide varistors, variable frequency drives, and LEDs.
