The paper first introduces the density of the mobile charges in a homogeneous conducting medium;then gives the understanding of the mobile charges and talks about the source and the meaning of the mobile charges and the relationship between the charges and the electric current in a homogeneous conducting medium. At the last the article expresses a whole and clear picture on the steady electric current fields'forming, keeping and disappearing.
