An Introduction to Electrical Science

by Adrian Waygood

Overview

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 City & 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 at those starting careers in electricity and 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 capacitors
• 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. There is also a companion website, with interactive multiple choice quizzes for each chapter and more, at www.routledge.com/cw/waygood
