Lightning

The process of transferring of charge from a charged object to the earth is known as earthing.

When negative and positive charges meet, it produces streaks of bright light and sound and the process is known as an electric discharge.The process of electric discharge also occurs between two or more clouds, or between clouds and the earth.

During the lightning and the thunderstorm no open place is safe.

Electrical appliances such as computers, TVs, etc., should be unplugged; however, electrical lights can be left on, as they do not cause any harm.

The device, used to protect buildings from the effect of lightning, is known as Lightning Conductor.

A metallic rod, taller than the building, is fixed in the walls of the building from top to toes during its construction protects from thunderstorm (as shown in the image given below).

The metal columns used during the fixing of electrical wires and water pipes in the buildings also protect from the thunderstorm and lightning.

If a thunderstorm occurs there is also a possibility of lightning and cyclones.
