## COURSE OBJECTIVES

This freshmen level course has been designed to provide an introduction to the ideas and concepts of Physics that would serve as a foundation for subsequent electronic engineering courses. The primary objective is to endow the knowledge of a wide variety of electromagnetic phenomena’s along with their scientific applications, specifically, in the field of electronic engineering. The course initiates with a short review of relevant mathematics, immediately followed by the basics of electricity at the atomic level. A majority of the course is then dedicated for electric and magnetic fields, forces, elements and their applications. Additionally, it also aims to provide introductory knowledge of wave theory and semi-conductor theory in conjunction with their applications.
