ELECTRICAL AND ELECTRONIC PRINCIPLES AND TECHNOLOGY

Abstract

Electrical and Electronic Principles and Technology, 6th 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. In this new sixth edition, new material added includes some mathematics revision needed for electrical and electronic principles, ways of generating electricity – the present and the future (including more on renewable energy), more on lithium-ion batteries and solar energy, along with other minor modifications. This sixth edition of the textbook provides coverage of the following latest syllabuses: (i) ‘Electrical and Electronic Principles’ (BTEC Level 3 Nationals Specification in Engineering, Unit 6) – see chapters 3–12, 13 (part), 14 (part), 16, 17 (part), 18 (part), 20 (part), 24 (part), 25 (part). (ii) ‘Further Electrical Principles’ (BTEC National Certificate and National Diploma, Unit 64) – see chapters 15, 17–20, 23, 25, 26. (iii) Parts of the following BTEC National syllabuses: Electrical Technology (Unit 51),Principles and operation of three-phase systems (Unit 62) and Three-phase motors and drives (Unit 63). (iv) Various parts of City & Guilds Technician Certificate/Diploma in Electrical and Electronic Engineering/Telecommunication Systems. (v) ‘Electrical and Electronic Principles’ (EAL Advanced Diploma in Engineering and Technology). (vi) Any introductory/Access/Foundation course involving Electrical and Electronic Engineering Principles. The text is set out in five main sections: Part 1, comprising chapters 1 and 2, involves Revision of Some Basic Mathematics needed for Electrical and Electronic Principles. Part 2, comprising chapters 3 to 14, involves essential Basic Electrical and Electronic Engineering Principles, with chapters on electrical units and quantities, introduction to electric circuits, resistance variation, chemical effects of electricity, series and parallel networks, capacitors and capacitance, magnetic circuits, electromagnetism, electromagneticinduction, electrical measuring instruments and measurements, semiconductors diodes and transistors. Part 3, comprising chapters 15 to 21, involves Further Electrical and Electronic Principles, with chapters on d.c. circuit theory, alternating voltages and currents, single-phase series and parallel networks, filter networks, d.c. transients and operational amplifiers. Part 4, comprising chapters 22 to 26, involves Electrical Power Technology, with chapters on ways of generating electricity – the present and the future, three-phase systems, transformers, d.c. machines and three-phase induction motors. Part 5, comprising chapter 27, details 10 practical laboratory experiments. 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.
