Abstract
The energy of a graph is the sum of the eigenvalues of its adjacency matrix. In this paper, we are interested in how the energy of a graph changes when edges in a graph are added or removed. We prove that the energy of a graph is increased or decreased. The energy of the graph depend upon edges due to edge addition or deletion. In this paper we are dealing with various families of wheel related graphs such as Jahangir graphs, wheels and fans.
