In cloud lightning
In cloud lightning is the most common type of lightning. This occurs between oppositely charged centers within the same cloud. This means that there are both positive and negative charges within the same cloud. Usually the process takes place within the cloud and looks like a bright flash of light which flickers. This bright flash may leave the cloud and the flash can be visible for many miles.
A less common lightning strike occurs between oppositely charged areas of different clouds. This means that there are positive and negative charges within different clouds and the strike travels in the air between them. This type of lightning is known as intercloud lightning.
