Hughes Electrical Technology has been established for over 30 years as the definitive work for all those studying electrical and electronic engineering from technician through to first year degree level. With over 50,000 copies of previous editions sold since publication in 1987 this text is the leader in its' class. The seventh edition represents the most thorough and radical revision of the text since the first edition was published, reflecting recent advances in technology and the changing requirements of today's courses. Reorganised into four sections, and incorporating two-colour illustrations, the new text puts a greater emphasis on electrical systems, and less on circuit analysis, and deals more thoroughly with electronics. The fundamental principles of electrical technology are clearly and simply outlined and then used to introduce the application of electrical and electronic systems. Power systems are discussed fully and the progression from analogue to digital systems is reflected in the extended coverage of digital techniques. New features for the seventh edition include: an increased number of worked examples, 140 additional pages of text, updated review questions, two-colour diagrams and text, improved chapter summaries including key equations, definitions of important terms, and lecturers guide
