Summary of Content

The aim of this module is to develop in the student an understanding of the fundamentals of electrical parameters and apply these fundamentals in the analysis of circuit theory to solve engineering problems required for initial design activities. It provides the student with the basic knowledge of ac and dc circuit analysis and to study capacitors, inductors and magnetic circuits and their applications.
