This textbook provides a foundational overview of electrical and electronic engineering principles tailored for students in non-electrical disciplines. Authors E. C. Bell and R. W. Whitehead utilize their academic expertise to bridge the gap between theoretical electrical concepts and the practical requirements of civil, chemical, and mechanical engineering students. The text emphasizes core principles while integrating updated information on digital systems and microprocessors to reflect the technological standards of the era.

The subject matter points to a pedagogical resource designed for undergraduate engineering students seeking a broad, practical introduction to electrical systems. The inclusion of updated technical modules and problem sets suggests a focus on academic utility and curriculum alignment for certificate and diploma programs.
