In the present paper, we introduce and investigate some properties on graph, also study some comparisons interior, closure, boundary and connectedness between graph concepts and approximation structure concepts. We initiate new scale by general forms of interior and closure on graph in three methods. We also discuss independence and dependence of two graphs through a new scale. We apply new concepts on electrical model to illustrate some properties on this model and the corresponding topological structure by using graph theory concepts.
