The electric fields due to lightning at ground was evaluated for static cases using the coulombs law. The concept of electrical image was developed considering ground as a conducting grounded plane. A tri-pole model for the charge structure of thundercloud was developed and electric fields due to such cloud structure were evaluated. Variations of electric fields due to distance were assessed and the expression of reversal distance was introduced. The graph describing the reversal distance from lightning was introduced.
