This text book covers the basics of DC circuit analysis. It could be considered as a valuable reference book. However, I would not consider it as a text book as it lacks problems. The links provided in the book would make this book a true electronic book. The book has limited examples for an introductory course. Multisim examples are quite useful.
The text book provides accurate information to the best of my knowledge.
DC circuit analysis is a traditional topic in all electrical engineering curricula around the world. The future updates to this book would be adding more examples, using other simulation software and adding problems. The arrangement would easily allow those updates.
The book is adequately clear. A chapter summary would be so helpful to the students. In module 3, adding a section on source free circuits will be a good introduction to this chapter.
The textbook is consistent in terms of topics or terminology, labeling, and format. The book is also consistent with major books in this field.
The text is professionally divided in modules. The sub-modules well serves the understanding of their modules.
The book is well organized. The sequence of the chapters is very logical. That well serves the understanding of the whole book.
The links I used worked well. The hand written Appendix A1 does not look professional.
I could not notice any grammatical errors.
I could not see any cultural issues.
In general, the book is a valuable free reference book.

This books provides both introductory and also in-depth information on the DC circuit fundamentals and associated components. It would have been really good if few more solved problems from each sections are included so the students using the book will get more practice problems. Including some practice questions at the end of the chapters (with or without answer key) is also something that would be useful.
I found the contents in the book accurate to the best of my knowledge.
This book talks about the fundamentals of the DC circuits in detail. I found this book relevant to the engineering curriculum.
When you look at the book first, the contents seems to be really densely packed, which might discourage a student who is really new to the topic. But when you read through the book, you can see that everything is explained well and in detail.
I found the book consistent in terms of the terminologies, topics covered, representation style and format.
The style of presentation of the book might be a little bit intimidating for a student in the freshman level introductory course and that might affect the modularity to some level. But I believe that if a student is willing to go through the textbook and get familiar with the layout , then it should make further navigation easy for them.
I think the book is organized well.
The book is presented well as far as interfacing is concerned. There are plenty of circuit diagrams created using Multisim that can be easily recreated in hardware or software if needed or can be used for practicing problem solving. The hyperlinks in the text also helps with better navigation.
The text contains no grammatical errors.
The contents are purely technical. So it has no cultural relevance.
This looks like a good resource for the students to refer for DC circuits topics. The book being part of the Open Textbook Library helps the students to easily access the contents.

Provides extensive information relating to DC circuits, but electromagnetism material is limited.
Author clearly demonstrates mastery of subject matter in simplifying series-parallel circuits. The preface gives the impression that the author has high credibility in the subject, having had much experience of explaining “a variety of DC circuit problems in a more efficient and simple manner than you normally find in circuits books (3).”
Introductory information is clear and concise, not too intimidating for beginning electronics students. Having drawings provided from MultiSim allows readers with access to the software to be able to reconstruct the schematics and obtain the results themselves, to verify their calculations.
RC charging capacitor circuit could be more simplified.
It would be nice for subscripts to be used more consistently in the labeling of resistors, but it is not crucial to understanding the concepts.
The modular structure of the book is similar to how DC portions of electronics courses are normally taught—beginning with the simplest of electronic fundamentals, introducing Ohm’s Law and Power Law, then providing series circuit and parallel circuit examples to introduce Kirchhoff’s Voltage Law and Kirchhoff’s Current Law, respectively. All this being introduced in Module 1 allows for a solid background before moving into more advanced electronics problems such as those found in Modules 2 and 3.
At the end of Modules 1 and 3 is a helpful equation list that can be referred to. Additionally, the digital bookmark links are very practical. However, the use of level headings and subsections could be better. For example, the Maximum Power Transfer Theorem should have its own section, but it is combined with Section 2.6 – Thevenin and Norton Equivalent Circuits.
At first glance, Appendix A.2 is labeled as Solving RLC circuits, but it solves an RL circuit and an RC circuit; I didn’t see any with both capacitors and inductors. This may have been intentional (referring to RL and RC circuits as RLC, but I misinterpreted). Other than that, I did not notice any issues.
Did not notice any problems.
Did not notice any problems. Author caters to beginners, intermediates, and experts alike.
Overall, Davis' DC Circuits is a great resource for those unable to pay the hundreds of dollars for conventional textbooks. An accompanying lab manual would be a great addition for future works.

Although thorough the book overall seems to lend itself to those having a strong background in math. Those in a technical program are a bit intimidated by the uses of matrices and long equations and will defer to their calculators, which is not presented here. I thought the material covered was the best I've seen in a while, but it did go rather quickly and there doesn't seem to be much in the way of problems students can fall back on to gauge varying degrees of comprehension. Also missing are applications where this information will be useful either now or later. Otherwise a good book to review the DC course materials in any basic electronics/electricity class. Just needs to go a bit slower. The use of MultiSim was very good as well. The most important missing bit of information I saw was that the author didn't use KVLs to complete the problems he wanted the student to find unknowns with. He relied on MultiSim and the use of a KVL or KCL appropriately would have been just as easy.
I found no errors in the book, nor any typos. It was nice to browse through a book that seems to be written by one individual instead of many.
It will last a lifetime. Already has with few exceptions.
Was a bit too wordy and seemed overwhelming to browse with the associated on-line materials. Perhaps the actual book is better. Needed to be spaced out a bit more so student can write notes with corresponding materials in case they have the book.
Stepped through all points of contention very well, though some points more quickly than others.
As I stated earlier, the ability to just browse and stay with the material is a bit daunting with all the findings cramped into a small space for a contextual look through MultiSim's eyes.
This follows the material exactly as I teach it.
I don't believe there are any problems with the graphics or links, only that they needed a bit more room to view.
I didn't find any grammatical errors.
There is no "person" involved in presenting this material to anyone. So, no cultural biases.
As I said, it's one of the best I've seen in a while. Just need more homework problems to really test the theoretical concepts and bring them to bear.

The book covers DC circuit analysis for resistive circuits and transient analysis for circuits with inductor and capacitors. It is good resource for the students to learn circuits analysis in the first semester for a two-semester circuits analysis sequence.
The book used Multisim software to draw the circuit schematic and conduct the simulation so that students can confirm their calculations using nodal or mesh analysis and be familiar with the circuit design and synthesis. The coverage of circuit theory seems fair and balanced.
The basic circuit theory does not change much. The book is relatively easy for students to read and practice with the practice examples.
The book is clearly written. It would be nice to have a summary for each chapter indicating the important concept and circuit analysis skills that students have to master. The Thevenin's equivalent circuit model deserves more coverage in showing the circuit modeling and synthesis skills useful for studying microelectronic circuits.
The book follows a natural sequence to introduce DC circuit analysis and then the first and second order transient circuits. What might be helpful is the coverage of operational amplifier circuits (e.g., inverting and non-inverting amplifier, addition, integration, differentiation).
The book has good modular sections covering the key skill set for DC circuit analysis.
The book is well organized.

About the Book
This book covers Direct Current (DC) circuit theory and is broken up into three modules. Module 1 covers the basics for circuits that include DC sources (voltage or current) and resistors. Even though Module 1 is not very difficult, it forms the foundation for more complicated topics in modules 2 and 3 so it is important to have a firm grasp of all Module 1 topics before moving on. Module 2 covers more difficult problem solving techniques for circuits that include only DC sources and resistors. Module 3 introduces capacitors and inductors. These non-linear reactive components are analyzed in the transient and steady state regions in circuits with DC sources in Module 3. Also annexed is a two-page cheat sheet that ENGR 2431 students at University of Oklahoma can use for exams.
