For those pursuing an electrical engineering degree, a strong foundation in mathematics and physics is essential. In addition to these subjects, studying introductory materials in systems and controls is recommended, as it can be complex and requires significant mathematical understanding. Key resources include engineering-oriented mathematics textbooks, as well as foundational books on electrical and electronic circuits, such as those by Sedra, Smith, Malvino, and Boylestad, which are considered essential for mastering the field. The Schaum's Outline series is also valuable for its numerous solved problems across various topics, aiding in comprehension and application. Practical Electronics for Inventors is suggested for its blend of theory and hands-on application, making it a useful reference for aspiring engineers.
