How does a lightning conductor protect a building

How does a lightning conductor protect buildings from lightning? Lightning conductors protect a building from lightning. Lightning conductors cannot protect a building from lightning. The lightning conductor cannot protect the building from lightning. True or False Lightning conductor cannot protect a building from lightning. Lightning conductor conducts the building with lightning.

Solution: A lightning conductor is a device used to protect buildings from the damaging effect of the lightning. Set your child up for success with Lido, book a class today! Maths Class 6 Class 7 Class 8. This conductor is struck first in lightning without hitting the building directly, preventing fire or electrocution.

It provides a harmless and easy path for the lightning energy to pass into the ground without damaging the structure of the buildings. The path or the earthing system is installed from the top to the bottom of the building. The conductor provides a poor resistance path between the top of the conductor rod through a substantial metal strip to the ground. Hence the current from the lightning strike is diverted through the rod and avoids flowing through the building.

The lightning conductor works on the principle of induction. When a fully charged cloud passes by the building, the conductor gets charged oppositely through the process of induction and this acquired charge moves to the earth through the earthing system. The electrical length of its rod will always be greater than its physical length.

The air becomes a conductor in the presence of a large electric field, and this electric field is strong around sharp objects than the objects where the surface is flatter. During the build-up of lightning, charges are induced at the top of the pointed lightning conductor rod by the cloud charge.

The effective length of the conducting path of the conductor is extended as the induced charge is sufficiently large and the air around the point of the lightning conductor.

Lightning conductor or Lightning rod is a metal rod or wire that fixed to an uncovered part of a building roof or other tall structure to collect lightning destruction and divert harmlessly into the ground. Fig Lightning Stroked at tallest building in a city center. So, the name lightning conductors recommends that it conducts the electric charge which come from cloud and hits on the building.

This simple equipment attract like magnetic action to lightning charges, harvest them and send to the ground through the wire connected with roof top lightning rod and buried metal plate at bottom. Do you interested to know more detail about. Difference Between Lightning and Surge Arrester? Specification of high voltage Surge Arrester.

Lightning rod or lightning conductor does not allow the electric charge to pass through the building material. No any metal in the building touches the lightning rod or conductor connected between rod and buried earthing plate, it must be isolated form other material of structure.

The lightning rod and conducting wire must be made of a good conducting material, like- Copper, Aluminum etc.
