Fundamental Electrical and Electronic Principles, Third Edition

IntroductionThe chapters follow a sequence that I consider to be a logicalprogression through the subject matter, and in the main, followthe order of objectives stated in the BTEC unit of Electrical andElectronic Principles. The major exception to this is that the topics ofinstrumentation and measurements do not appear in a specific chapterof that title. Instead, the various instruments and measurement methodsare integrated within those chapters where the relevant theory iscovered.Occasionally a word or phrase will appear in bold blue type, and closeby will be a box with a blue background. These emphasised words orphrases may be ones that are not familiar to students, and within thebox will be an explanation of the words used in the text.Throughout the book, Worked Examples appear as Q questionsin bold type, followed by A answers. In all chapters, AssignmentQuestions are provided for students to solve.The first chapter deals with the basic concepts of electricity; the use ofstandard form and its adaptation to scientific notation; SI and derivedunits; and the plotting of graphs. This chapter is intended to providea means of ensuring that all students on a given course start with thesame background knowledge. Also included in this chapter are notesregarding communication. In particular, emphasis is placed on logicaland thorough presentation of information, etc. in the solution ofAssignment Questions and Practical Assignment reports.xi
