As a young child, you probably had trepidations about lightning, but did you ever wonder how it worked? To illustrate, let us visualize a cloud. Often time, there is internal movement inside the cloud, which leads to movement of charge inside the cloud. This leads to Polarization of the cloud. This buildup of electrons will have further effects on the ground level, with the negative electrons being pushed away and the positive charge being attracted to the cloud. In fact, all objectives within the vicinity will become polarized. This buildup of opposing charges will create a voltage. If the voltage grows high enough, then a dielectric breakdown will occur through the air, turning it from an insulator to a conductor, and creating a bolt of lightning.
