I agree with you. I have a degree in electrical engineering and use that book to quickly remind myself how something that I haven't used in a long time works and get an overview of practical do's and don'ts. If I had tried learning the basics of electrical circuits from it, I think I'd become discouraged very quickly.
It was pretty much my introduction to circuits, and had it not been used in a class with a significant lab component I would have also been discouraged. Great reference, but not good for teaching yourself unless you're very comfortable being confused or have had prior exposure to the material.
