In this paper we present a new graph that is closely related to the total graph of rings. Let R be a commutative ring and Z(R) be the set of all zero divisors of R. The extended graph of a commutative ring R is the graph GT(T(R)) with all elements of R as vertices and two nonzero distinct elements x,yER are adjacent if and only if there exist positive integers m and n such that xm+ynE Z(R) . The main purpose of this paper is to extend the definition and some results given in [2].
