Basic Electric Circuit Analysis - D. E. Johnson, J. L. Hilburn, and J. R. Johnson [Book Reviews]

The reviewer feels the presentation of material in this text is logical and easily understood. Some examples however, suffer due to brevity of explanation. It is often necessary to give very detailed explanations for beginning students and this book sometimes falls short of that. Perhaps the most confusing thing about the entire book is the introduction of operational amplifiers early in the book. The number of new concepts introduced in this course is large enough without adding one that might be better left for an introductory electronics course. The most often heard complaint from students using the text in the classroom was that a large number of exercises and problems refer to previous exercises or problems. Some of these referred to problems themselves referring to earlier problems. This means that the student must be paging back and forth to assemble all the information to work a given problem. It would be far better to repeat a circuit diagram or set of conditions than to have to search through the book so much to get the statement of a problem.
