Graph Theory was born in 1736 when Leonhard Euler published “Solutio problematic as geometriam situs pertinentis” (The solution of a problem relating to the theory of position) (Euler, 1736). It leads to graph practically not possible to analyze without the aid of computer. 1. 1 / 20 L. Joyprakash Singh (ECE, NEHU) EE-304 ENT :: Network topology and graph. Graphs and networks A graph is a collection of nodes joined by edges; Figure 1 shows one small graph. Thus, network analysis, the basis of network theory, plays a central and essential role in system analysis.

For example, given a graph G= (V;E), we de ned an adjacency matrix Aand considered the eigensystem Av= v, and we also de ned the Electrical shock occurs when the body becomes part of the electric circuit, either when an individual comes in contact with both wires of an electrical circuit, one wire of an energized circuit and the ground, or a metallic part that has become energized by contact with an electrical conductor. Ever since, graph theory has been used in electrical network theory and analysis.
