Heavily updated and expanded, this second edition of Adrian Waygood’s textbook provides an indispensable introduction to the science behind electrical engineering.

While fully matched to the electrical science requirements of the 2330 levels 2 and 3 Certificates in Electrotechnical Technology from the City and Guilds (Electrical Installation), the main purpose of this book is to develop an easy understanding of the how and why within each topic. It is aimed for those starting careers in electronics, as well as any hobbyists, with an array of new material to reflect changes in the industry.

New chapters include:

  • Electrical Drawings
  • Practical Resistors
  • Measuring Instruments
  • Basic Motor Action
  • Practical Inductors
  • Basic Transformer Theory
  • The Electricity Supply Industry
  • …and more

The author details the historical context of each main principle and offers a wealth of examples, images and diagrams, all whilst maintaining his signature conversational and accessible style. And there is also a companion site with interactive multiple choice quizzes for each chapter and more, at
