This is designed as a pocket reference for undergraduate electrical engineering. It includes theories, solvers, and examples for fundamental EE courses listed as follows: + circuits, + digital, + power systems, and fields. There is also a reference section that provides a refresher in math and units as applied to electrical engineering. Emphasis is placed on basic circuit theory such as: + impedance, + magnitude, + phase angle, + series circuits, + parallel circuits, etc. Even though this is intended for the undergrad EE student, this also provides a quick reference for the engineers, hobbyists, scientists, or just enthusiasts of circuits.
