Abstract

The characteristic of a ring 𝑅, denoted by 𝛹(𝑅), is the smallest positive integer n such that 𝑛𝑟 = 0 for all 𝑟 ∈ 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.
