Atmospheric Physics

Treating the Earth and the cloud as a parallel plate capacitor, we can estimate the current of lightning. Suppose the base of a storm cloud is 3km above ground, with a surface area roughly \({10}^{8} {m}^{2}\). If the dielectric constant of air is approximately 1 and the potential difference of the Earth-cloud system is \({10}^{8} V\), what would the average current (in Amperes) be if the electric energy is discharged in 0.2 seconds?

Submit the answer to the nearest integer.
