The established textbook bridges the gap between the technical knowledge for electrical professions taught in vocational schools and the mathematical-physical foundations of electrical engineering found in higher education literature. It primarily targets trainees in technical schools, but it also serves as a helpful introduction to electrical engineering for students in their early semesters at universities of applied sciences and technical universities. The 6th edition has been revised and updated. The authors have incorporated numerous exercises and worked examples, with solutions conveniently located at the end of the book.
