IEEE Student Chapter of Dronacharya College of Engineering, Gurgoan organized a guest lecture on “BASICS OF NETWORK THEORY” for ECE and EEE III semester students on 3rd October 2016 by Prof. B.K. Panigrahi , IIT Delhi.

The objective of the lecture was to explore the technical aspects, contemporary applications in Network Theory.

Prof. Panigrahi during his lecture briefed about basics of Network Theory, Energy Sources, Various Network Theorems, Transient analysis, AC & DC analysis of RLC circuits and various applications of network theory.

In the first session Prof. Panigrahi explained that Network theory provides a set of techniques for analyzing graphs and complex systems network theory provides techniques for analyzing structure in a system of interacting agents, represented as a network. He stated applying network theory to a system means using a graph - theoretic representation. Discussing voltage and current sources he explained a voltage source is a two terminal device which can maintain a fixed voltage whereas a current source is an electronic circuit that delivers or absorbs an electric current which is independent of the voltage across it. He also explained voltage and current inter-conversion.

After that, he explained various circuit analysis theorems like, Maxwell’s loop law, Nodal analysis, Thevenin’s theorem, Norton’s theorem, Maximum Power Transfer Theorem, Tellen’s theorem, Reciprocity theorem, Star - delta network and numerical on equivalent resistances. After each theorem’s explanation, he gave some practice questions to the students. He also solved various numerical based on these theorems.

In the next session he explained the R-L, R-C, and R-L-C circuit. He described a resistor - capacitor circuit (RC circuit), is an electric circuit composed of resistors and capacitors driven by a voltage or current source, a resistor - inductor circuit (RL circuit), is an electric circuit composed of resistors and inductors driven by a voltage or current source and an RLC circuit is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel. He also discussed the transient response of R-L, R-C, and R-L-C series parallel circuits. Then he explained AC & DC analysis of RLC circuits.

Talking about the application of Network theory he explained Network theory lies at the intersection of many areas, including mathematics, computer science, electronic engineering, computer engineering, and operations research.

The session was extremely informative and useful for the students. The students participated very well by answering questions and solving numerical problems.
