Electrical and Electronic Principles and Technology, 3rd Edition introduces the principles which describe the operation of d.c. and a.c. circuits, covering both steady and transient states, and applies these principles to filter networks, operational amplifiers, three-phase supplies, transformers, d.c. machines and three-phase induction motors. New topics included in this edition are a complete update on semiconductor diodes and transistors, and additional material on batteries, fuel cells and alternative and renewable energies, relative and absolute voltages, self and mutual inductance, virtual test and measuring instruments.
In addition, applications in all areas are expanded and emphasised and some new further problems added. A new feature of this third edition is that a free Internet download (lecturers only) is available of a sample of solutions (some 400) of the 530 further problems contained in the book — see below. Another new feature is a free Internet download (available for lecturers only) of all 517 illustrations contained in the text — see below.

The text is set out in three main sections:
Section 1, comprising chapters 1 to 12, involves essential Basic Electrical and Electronic Engineering Principles, with chapters on electrical units and quantities, introduction to electric circuits, resistance variation, batteries and alternative sources of energy, series and parallel networks, capacitors and capacitance, magnetic circuits, electromagnetism, electromagnetic induction, electrical measuring instruments and measurements, semiconductor diodes and transistors.
Section 2, comprising chapters 13 to 19, involves Further Electrical and Electronic Principles, with chapters on d.c. circuit theorems, alternating voltages and currents, single-phase series and parallel networks, filter networks, d.c. transients and operational amplifiers.
Section 3, comprising chapters 20 to 23, involves Electrical Power Technology, with chapters on threephase systems, transformers, d.c. machines and threephase induction motors. Each topic considered in the text is presented in a way that assumes in the reader little previous knowledge of that topic. Theory is introduced in each chapter by a reasonably brief outline of essential information, definitions, formulae, procedures, etc. The theory is kept to a minimum, for problem solving is extensively used to establish and exemplify the theory. It is intended that readers will gain real understanding through seeing problems solved and then through solving similar problems themselves.
Electrical and Electronic Principles and Technology, 3rd Edition contains 400 worked problems, together with 340 multi-choice questions (with answers at the back of the book). Also included are over 450 short answer questions, the answers for which can be determined from the preceding material in that particular chapter, and some 530 further questions, arranged in 145 Exercises, all with answers, in brackets, immediately following each question; the Exercises appear at regular intervals — every 3 or 4 pages — throughout the text.

Over 500 line diagrams further enhance the understanding of the theory. All of the problems — multi-choice, short answer and further questions — mirror practical situations found in electrical and electronic engineering. At regular intervals throughout the text are seven Revision Tests to check understanding. For example, Revision Test 1 covers material contained in chapters 1 to 4, Revision Test 2 covers the material contained in chapters 5 to 7, and so on. These Revision Tests do not have answers given since it is envisaged that lecturers/instructors could set the Tests for students to attempt as part of their course structure. Lecturers/instructors may obtain a free Internet download of full solutions of the Revision Tests in an Instructor’s Manual — see below.
I am very grateful to Mike Tooley for his help in updating chapters on Semiconductor diodes, Transistors, and Measuring instruments and measurements. A list of relevant formulae is included at the end of each of the three sections of the book. ‘Learning by Example’ is at the heart of Electrical and Electronic Principles and Technology, 3rd Edition.
