the physics of lightning
Lightning is the result of the build up of electrostatic charge in clouds. Positive and negative charges separate, negative usually towards the bottom of the cloud, while positive goes to the top.After a certain amount of time, the negative charge leaps, connecting with either another cloud or even the ground.hen these negative and positive charges connect, a return stroke occurs. The result is a bright, flickering flash of light, which is usually followed by a rumble of thunder. Lightning is a form of electricity. Benjamin Franklin discovered this in his well-known key and kite experiment.
