I'd like to learn about how the fundamentals of how power works and how circuit theory works, while actually keeping a continuum between the fundamentals. In otherwords, I have a BS in physics, and am MSEE, picked up a book on circuit theory, and it was filled with rules with no physics-backed explanations. I understand some concepts are built on a higher level, and it's sometimes futile to dive into the physical explanations entirely. Any great textbooks to read and keep on the shelf for Power Circuit Theory ? BS Physics MS Electrical Engineering I am just looking for the names of some texts to pick up to flip through, and that are worthy to keep around. I learned out of the book all through college and grad school anyway.
