Capacitors 101
Lightning, a naturally occurring phenomenon, works very similar to a capacitor. The cloud is one of the plates and the earth is the other. Charge slowly builds-up between the cloud and the earth. When this creates more voltage than the air (the dielectric) can bear, the insulation breakdown causes a flow of charges between the two plates in the form of a bolt of lightning.
