A simplified approach to understanding of the phenomenon of cloud to ground lightning and modeling of return stroke current

Lightning is typically an atmospheric phenomenon and is a threat to human life, houses, historical monuments, electronic and electrical systems. Through a good will of research the scientific community has come to some conclusion about the cause of lightning and its hazards to system. In this paper the generation process of Cloud to ground lightning is described in brief and the most harmful one, the return stroke has been modeled. The reason behind taking return stroke in all formulation related to lightning is it´s continuous nature. Other forms are branched and therefore discontinuous.
