This book is impossible to use. The homework problems have very little relation to the material and are much harder than any examples presented in the text. It'd be nice to have a professor to clue me in (if mine could figure this book out either...), but you should be able to get more from the textbook itself than this one provides.
The book is sloppily put together and laid out so that most of the time material that should be on one page together end up with half on each side of a page, making you flip back and forth between explanations and diagrams or two connected formulae. This makes it hard to skim for information. The material seems thrown at you arbitrarily. For instance, an explanation of branches, nodes, and loops comes in chapter 4, when that should have been covered from the beginning.
In most areas, the text also leaves out nuances that students with no previous circuit analysis experience need. As an example: The concept of a node and what can be considered a node is never made explicitly clear. The book expects you to make do with the idea that a node is a black dot on a circuit diagram, but at the same time expects you to know when you can reduce nodes in a transformation. Since this book is being used in a first-year electric circuits course with no prerequisite knowledge of electric circuits, all of these ommissions make learning the material much harder than it needs to be. It's as if the text was written by engineers for engineers, not for engineering students. The authors have clearly forgotten what it was like to learn this stuff the first time around, or else they are sadists.
I will also go on to describe the website connected to this text, since if the publisher has duped your school into using their site for homework, you will be forced to use it, at extra cost, in conjunction with this atrocity of book. You will be sad to see that the video solutions on the site are only to the most simple problems - nothing like what is actually graded. Their "study guides" only cover the first parts of the chapters and again are too simple to be of value. There is zero feedback if you get something wrong on the homework, so you will never know what mistake you made - which might have been as simple as formatting your answer incorrectly, because the site is ridiculously picky.
Maybe I am just stupid or something, but this book makes me want to shoot myself in the face. You will cry if you ever have to use this book, I promise. You will cry until your floors are soaked in salty tears and your downstairs neighbors complain of water damage to their ceiling.
A more suitable text for a beginning student is Electric Circuit Analysis by Charles J. Monier. I only hope I've found it in time to save my grade.
