Application of Lightning Rod

What is a Lightning Rod?

a lightning rod or a lightning conductor is a simple pointed metal rod attached to the roof of a tall building to prevent damages for the building, invented by Benjamin Franklin. The rod will conduct the lightning safely to the ground by special braided cables. lightning rods came in many different forms, including hollow, solid, pointed, rounded, flat strips or even bristle brush-like. the main point of all lightning rods is that they are conductive. copper and its alloys are the most common materials used in lightning protection.

How Lightning rods work?

A lightning rod attract lightning so they do not hit the building. It will discharge the air around them and lessen the chance of lightning striking them. If the charge is large enough, the lightning will discharge in a controlled manner through the lightning rod and into the ground without doing damage.

The importance of lightning rod

It gives the lightning a ground to dissapate the stored electricity, instead of usind a house or a building. It keeps the lightning from starting a fire or damaging a house.

The purpose of lightning rod is not to attract lightning, a lightning rod on a tall building is to also help the community around it. The rod will bleed charge off the storm, as a result it does not strike. It will let the lightning hit the lightning rod while grounding it, instead of letting the lighting to hit somewhere else and make damages on other buildings and objects.

Lightning Rods
In conclusion, lightning rods benefit our society by bleed charging the storm first, if strikes are made the lighting rod will ground the strike instead of letting it to hurt the building and ourselves.
