The typical curriculum of an undergraduate electrical engineering student includes the subjects listed in Table 1.1. Although the distinction between some of these subjects is not always clear-cut， the table is sufficiently representative to serve our purposes. Figure 1.1 illustrates a possible interconnection between the disciplines of Table 1.1. The aim of this book is to introduce the non-electrical engineering student to those aspects of electrical engineering that are likely to be most relevant to his or her professional career. Virtually all of the topics of Table 1.1 will be touched on in the book， with varying degrees of emphasis. The following example illustrates the pervasive presence of electrical， electronic， and electromechanical devices and systems in a very common application： the automobile. As you read Table 1.1 Electrical through the example， it will be instructive to refer to Figure 1.1 and Table 1.1.
