What is the principle used in a lightning conductor

Damages due to electric flashes are very common. But with the help of electrical conductors we can save our big buildings on which we have spent a lot of money.

Light conductors have a large number of conductors that have pointed heads. They are usually attached on top of buildings. Their pointing heads are attached to a conductor material such as copper wire. Then this copper wire of great length came down on both sides of the building. At the bottom, it is attached to a metal plate. The metal plate is then pressed into the ground. Clouds have mostly positive charges. Whenever the path of cloud is over a certain building, induced charges will occur. Induced pointing to the conductor will produce positive charge and induced negative charge will be produced on the metal plate. The pointed head of the conductor has the property of discharging the positive charge present on it. Due to the discharge of positive charge from the head, a positively charged air will be produced. Due to this wind, the negative charge of the cloud will be retaliated, that is, it will be canceled. After discharging, the cloud charge will flow to the ground with the help of copper wire.

Therefore by using this electrical conductor our building will be saved.

Now check the action of sharp edges of the indicator conductor.

As we know that the surface charge density of a spherical conductor is calculated by the formula. But we have to find the density in the case of a pointed conductor. The radius R for a specified conductor will be smaller.

Will be increased by a large amount. Small particles of air that come in direct contact with the gesture, and will receive the same charge as the head of the conductor. Similar charges will cause repulsion. The above reason produces electrically charged air, which continuously starts moving the charge from the pointing ends of the conductor. In other words we can say that disposal / spraying works. This phenomenon is so called corona discharge.

So, it is clear that spherical conductors with small radi can never be used to store charge. The charging of the conductors should be large for the charge. Renown Power
