Lightning is a visible electrical discharge from a cloud. This happens when there is an imbalance of charges between a region of the cloud and another surface (usually the ground, a building, another region of the same cloud, or another cloud) that is significant enough to break through air resistance.
How does electric discharge occur in lightning?
Lightning is an electrical discharge produced to balance the differences between positive and negative charges within a cloud, between two clouds, or between the cloud and the ground. … A negative charge at the base of the cloud is attracted to a positive charge at the earth’s surface.
How is electrical charge distributed through a thunderstorm?
The charges on the ground are influenced by the charge build up in the clouds. Normally, the ground has a slight negative charge however, when a thunderstorm is directly overhead, the large negative charge in the middle of the storm cloud repels negative charges on the ground underneath the storm.
What happens to electrical energy during a thunderstorm?
The imbalance of energy builds up until a bolt of lightning is released, either from cloud to ground or cloud to cloud, restoring the electrical balance of the atmosphere. Eventually, the storm will pass and the atmosphere’s natural equilibrium will be restored.

Which is safest in a thunderstorm?
If you hear the sound of thunder, go to a safe place immediately. The best place to go is a sturdy building or a car, but make sure the windows in the car are shut. Avoid sheds, picnic areas, baseball dugouts and bleachers. If there is no shelter around you, stay away from trees.
What causes lightning to strike a person?

Is it OK to watch TV during a thunderstorm?
It isn’t dangerous to watch TV during a thunderstorm, but the electronics in a TV set are vulnerable. If you have to make a telephone call, use a mobile phone detached from its cable rather than a landline device. Over-voltages resulting from a lightning strike may follow electrical conductors into the handset.
Is it safe to use WiFi during a thunderstorm?
