How Lightning is formed

Lightning is a physical phenomenon resulting from reverse charges in clouds or on ground.

The sky is filled with electric charge. In a calm sky, the positive (+) and negative (-) charges are evenly spaced throughout the atmosphere. Therefore, a calm sky has a neutral charge.

Two types of Lightning:

- Cloud to ground (CG): Cloud-to-ground is the best known and third most common type of lightning. Lightning can occur with both positive and negative polarity. The polarity is that of the charge in the region that originated the lightning leaders.

- Cloud to cloud (CC) and intra-cloud (IC): Lightning discharges may occur between areas of cloud without contacting the ground. When it occurs between two separate clouds it is known as inter-cloud lightning, and when it occurs between areas of differing electric potential within a single cloud it is known as intra-cloud lightning. Intra-cloud lightning is the most frequently occurring type

The potential difference between two surfaces: one is positive and another is negative: once two Clouds are connected while one side is negatively charged and the other is positively charged, trying to neutralize one another its strikes light and sound.

These charges once connected, make short circuit and a sound is produced due to the forces continued in these circuits.

Natural conductors like rain, trees, and metals, human, animal; etc can facilitate the connection of these charges.

The lightning affects all these mentioned good conductors cited above.
