Looking back over the last twelve editions of the text, it is interesting to find that the average time period between editions is about 3.5 years.
This thirteenth edition, however, will have 5 years between copyright dates clearly indicating a need to update and carefully review the content. Since the last edition, tabs have been placed on pages that need reflection, updating, or expansion.
The result is that my copy of the text looks more like a dust mop than a text on technical material. The benefits of such an approach become immediately obvious—no need to look for areas that need attention—they are well-defined.
In total, I have an opportunity to concentrate on being creative rather than searching for areas to improve.
A simple rereading of material that I have not reviewed for a few years will often identify presentations that need to be improved. Something I felt was in its best form a few years ago can often benefit from rewriting, expansion, or possible reduction.
Such opportunities must be balanced against the current scope of the text, which clearly has reached a maximum both in size and weight.
Any additional material requires a reduction in content in other areas, so the process can often be a difficult one.
However, I am pleased to reveal that the page count has expanded only slightly although an important array of new material has been added.
In this new edition, some of the updated areas include the improved efficiency level of solar panels, the growing use of fuel cells in applications including the home, automobile, and a variety of portable systems, the introduction of smart meters throughout the residential and industrial world.
The use of lumens to define lighting needs, the growing use of LEDs versus fluorescent CFLs and incandescent lamps, the growing use of inverters and converters in every phase of our everyday lives, and a variety of charts, graphs, and tables.
There are some 300 new art pieces in the text, 27 new photographs, and well over 100 inserts of new material throughout the text.
Perhaps the most notable change in this edition is the removal of Chapter 26 on System Analysis and the breaking up of Chapter 15, Series and Parallel ac Networks, into two chapters.
In recent years, current users, reviewers, friends, and associates made it clear that the content of Chapter 26 was seldom covered in the typical associate or undergraduate program. If included in the syllabus, the coverage was limited to a few major sections of the chapter.
Comments also revealed that it would play a very small part in the adoption decision. In the dc section of the text, series and parallel networks are covered in separate chapters because a clear understanding of the concepts in each chapter is critical to understanding the material to follow.
It is now felt that this level of importance should carry over to the ac networks and that Chapter 15 should be broken up into two chapters with similar titles to those of the dc portion of the text.
The result is much-improved coverage of important concepts in each chapter in addition to an increased number of examples and problems.
In addition, the computer coverage of each chapter is expanded to include additional procedures and sample printouts.
There is always room for improvement in the problem sections. Throughout this new edition, over 200 problems were revised, improved, or added to the selection.
As in previous editions, each section of the text has a corresponding section of problems at the end of each chapter that progress from the simple to the more complex.
The most difficult problems are indicated with an asterisk. In an appendix, the solutions to odd-numbered selected exercises are provided.
For confirmation of solutions to the even-numbered exercises, it is suggested that the reader consider attacking the problem from a different direction, confer with an associate to compare solutions or ask for confirmation from a faculty member who has the solutions manual for the text.
For this edition, a number of lengthy problems are broken up into separate parts to create a step approach to the problem and guide the student toward a solution. As indicated earlier, over 100 inserts of revised or new material are introduced throughout the text.
Examples of typical inserts include a discussion of artificial intelligence, analog versus digital meters, the effect of radial distance on Coulomb’s law, recent applications of superconductors, maximum voltage ratings of resistors, the growing use of LEDs
Lumens versus wattage in selecting luminescent products, ratio levels for voltage and current division, the impact of the ground connection on voltage levels, expanded coverage of shorts and open circuits.
The concept of 0+ and 0-, total revision of derivatives and their impact on specific quantities, the effect of multiple sources on the application of network theorems and methods, networks with both dc and ac sources, T and Pi filters, Fourier transforms, and a variety of other areas that needed to be improved or updated.
Both PSpice and Multisim remain an integral part of the introduction to computer software programs. In this edition, Cadance’s OrCAD version 16.6 (PSpice) is utilized along with Multisim 13.0 with coverage for both Windows 7 and Windows 8.1 for each package.
As with any developing software package, a number of changes are associated with the application of each program.
However, for the range of coverage included in this text, most of the changes occur on the front end so the application of each package is quite straightforward if the user has worked with either program in the past.
Due to the expanded use of Multisim by a number of institutions, the coverage of Multisim has been expanded to closely match the coverage of the OrCAD program. In total, more than 90 printouts are included in the coverage of each program.
There should be no need to consult any outside information on the application of the programs. Each step of a program is highlighted in boldface roman letters with the comment on how the computer will respond to the chosen operation.
In general, the printouts are used to introduce the power of each software package and to verify the results of examples covered in the text.
In preparation for each new edition, there is an extensive search to determine which calculator the text should utilize to demonstrate the steps required to obtain a particular result.
The chosen calculator is Texas Instrument’s TI-89 primarily because of its ability to perform lengthy calculations on complex numbers without having to use the time-consuming step-by-step approach.
Unfortunately, the manual provided with the calculator is short in its coverage or difficult to utilize. However, every effort is made to cover, in detail, all the steps needed to perform all the calculations that appear in the text.
Initially, the calculator may be overpowering in its range of applications and available functions. However, using the provided text material and being patient with the learning process will result in a technological tool that can do some amazing things, saving time and providing a very high degree of accuracy.
One should not be discouraged if the TI-89 calculator is not the chosen unit for the course or program. Most scientific calculators can perform all the required calculations for this text. The time, however, to perform a calculation may be a bit longer but not excessively so.
The laboratory manual has undergone some extensive updating and expansion in the able hands of Professor David Krispinsky. Two new laboratory experiments have been added and the number of experiments has been expanded to provide additional experience in the application of various meters.
The computer sections have also been expanded to verify experimental results and to show the student how the computer can be considered an additional piece of laboratory equipment.
Through the years I have been blessed to have Mr. Rex Davidson of Pearson Education as my senior editor. His contribution to the text in so many important ways is so enormous that I honestly wonder if I would be writing a thirteenth edition if it were not for his efforts.
I have to thank Sherrill Redd at Aptara Inc. for ensuring that the flow of the manuscript through the copyediting and page proof stages was smooth and properly supervised while Naomi Sysak was patient and meticulous in the preparation of the solutions manual.
My good friend Professor Louis Nashelsky spent many hours contributing to the computer content and preparation of the printouts. It’s been a long run—I have a great deal to be thankful for.
The cover design of the US edition was taken from an acrylic painting that Sigmund Årseth, a contemporary Norwegian painter, rendered in response to my request for cover designs that provided a unique presentation of color and light.
A friend of the author, he generated an enormous level of interest in Norwegian art in the United States through a Norwegian art form referred to as rosemaling and his efforts in interior decoration and landscape art.
All of us in the Norwegian community were saddened by his passing on 12/12/12. This edition is dedicated to his memory.
