Electrical Craft Principles

These books cover the electrical principles syllabuses of all the major examining bodies, including the City & Guilds of London Institute's electrical craft courses. The book is well illustrated with over 200 line diagrams and photographs. Theories are explained with the help of worked examples and there are more than 300 (400 in volume 2) graded exercises for which numerical answers are provided as well as over 300 multiple choice questions with solutions.

This is the second of a two-volume work covering the electrical principles syllabuses of all of the major examining bodies including the City & Guilds of London Institute's electrical craft courses. It is also suitable for a wide range of other courses, including the first three years of the BTEC electrical series. Great care has been taken to ensure that the text fully covers the content of the syllabuses concerned, both as published and as interpreted by the examiners in the past.

The two volumes of Whitfield's Electrical Craft Principles have been substantially revised and updated in 2008, reflecting changes in practice and legislation (e.g. BS 7671/Requirements for Electrical Installations). The volumes are presented in a new format, are highly illustrated and contain full problems and solutions.

The following topics are dealt with: capacitance and capacitors; inductance and inductors; magnetic materials and iron losses; alternating current theory; power in alternating current circuits; transformers; electrical generator; direct current machines; alternating current motors; electrical measuring instruments; lighting; and supply economics

The book comprises 15 chapters dealing with the following subjects: basic electrical units and circuits; resistance and resistors; mechanics; heat; electrical power and energy; permanent magnetism and electromagnetism; applications of electromagnetism; electric cells and batteries; electromagnetic induction; basic alternating-current theory; electrical motor principles; practical supplies and protection; cables and enclosures; lighting and heating installations; and introduction to electronics. Each chapter concludes with a summary of the formulas introduced in it. A complete list of symbols, abbreviations, and units is included. Numerical answers to exercises are provided
