I really enjoyed reading this book. Years ago I took an electrical (analog) circuits class in college. I didn't pay as much attention to it as I could have, since I was more interested in digital logic at the time. Lately, though, I've been wanting to tinker a bit more with circuits, including analog.
This book did a great job of giving me the refreshers I needed. It covers the basics by focusing on components: first resistors, then capacitors and inductors. Direct current is discussed first, with good alternating current explanations following in their own section. The book then continues with diodes, transistors (BJTs and FETs) and a high-level overview of integrated circuits.
From the perspective of someone who has already been exposed to this before, it was nearly perfect as a conceptual refresher. The discussions stay fairly high-level, but provide enough equations to allow for concrete explanations. Primarily, the computations seem focused on helping readers to understand how not to burn out the components in their circuits by selecting appropriate parts.
If this is your first introduction to electronics, it may seem a bit daunting. It will provide a good deal of background for understanding circuits, but doesn't go into any real depth on developing actual circuits. It's focus is more on helping you to understand circuits that someone else made, rather than on helping you create circuits of your own.
For me, though, this was very nearly perfect. It kept me interested and taught me quite a bit. (And, they should get extra points for providing an appendix section in the back discussing vacuum tubes for those of us who are simply curious.)
