The actual diameter of a lightning channel is one-to two inches. A typical cloud-to-ground flash is a negative stepped leader that travels downward through the cloud, followed by an upward traveling return stroke.

Less common, a downward traveling positive leader followed by an upward return stroke will lower positive charge to earth.
