I'm trying to decide whether to get the Spinup book or a couple of the Complex Imaginary books to help study for the Power section in October. Any thoughts? If I went with the Complex Imaginary, which volumes are the most helpful?
Definitely use all four to study to get started but i can tell you from taking the exam twice, studying those books is like taking a paintball gun to a real war zone. Besides studying those, i recommend you concentrate a lot more on power engineering books. Theodore's wildi electrical machines book is a tremendous help, at least to me.
