Preamble: This course introduces the basic concepts of circuit analysis which is the foundation for all subjects of the Electrical Engineering discipline. The emphasis of this course is laid on the basic analysis of circuits which includes single phase circuits, magnetic circuits, network theorems, transient analysis and network topology.

Course Objectives:

• To study the concepts of passive elements, types of sources and various network reduction techniques.
• To understand the applications of network topology to electrical circuits.
• To study the concept of magnetic coupled circuit.
• To understand the behavior of RLC networks for sinusoidal excitations.
• To study the performance of R-L, R-C and R-L-C circuits with variation of one of the parameters and to understand the concept of resonance.
• To understand the applications of network theorems for analysis of electrical networks
