Buy AN INTRODUCTION TO ELECTRICAL SCIENCE 2ND EDITION | Technical Books, New Arrivals

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
