Abstract
The characteristic of a ring R, denoted by ψ(R), is the smallest positive integer n such that nr =0 for all r ε R. If no such integer exists, we say that R has characteristic 0. In this article, the characteristic of a ring (R,+,.) is presented in terms of the order of the elements in the commutative group (R,+). Also it has been shown that the prime generators of o(R) and ψ(R) are same. This article also gives a relationship among ψ(R),ψ(I) and ψ(R/I) for any ring R and any ideal I of R.
