Electrical Network Analysis (EE-218)

To equip the students with the knowledge and techniques of analyzing electrical networks. The course introduces the analysis of AC circuits (comprising resistors, capacitors, and inductors) excited by sinusoidal sources. 2nd  ODE (RLC Circuits). The concept of complex frequency, single-phase circuit analysis, Phasors, complex impedance, star-delta transformation, Power Analysis, Application of Laplace Transforms in circuits analysis, and understand the two-port network. The purpose is to make students familiar with the modern hierarchy of AC circuits analysis and explain to them the state-of-the-art electrical network analysis.
