WHY YOU SHOULD USE LIGHTNING RODS?<\/b><\/i><\/b><\/i><\/h2>\n

<\/b><\/i>Lightning is an electrical discharge that keeps the increased electricity potential between earth and the clouds in balance. Since lightning is the contact of lightning bolt with earth, we first need to understand how lightning bolt is formed. Lightning bolt occurs due to charging of clouds. Well, the response to the question as to why clouds get charges could be that air is not a good conductor. Even though lightning strikes and interactions can be explained, humans\u2019 knowledge on how clouds get charged is not at a sufficient level. Throughout history lots of theories have been put forward on this subject. One of these theories is Simpson and Lomonosow\u2019s theory. According to this theory, charges in the clouds are formed with the assistance of air flow.<\/p>\n

\"\"<\/a><\/p>\n

Air flow, created as a result of shifting of hot and cold air, causes the water droplets in clouds to start moving. Water droplets in motion get charged by rubbing against each other. Air flows in the clouds cause water droplets to separate and then merge again. According to research, large water droplets, meaning the positively charged droplets, are located in lower parts of the clouds while small water droplets, meaning the negatively charged ones are located in the upper part, however according to research done, while the probability of the lower part of the cloud to be positively charged is between 0 and 10%, the probability to be negatively charged is between 80 and 95%. And this invalidates the theorem. Therefore, even if how it is charged is not explained, charged clouds do appear. Due to physical conditions, as a cloud is formed, the lower part of the cloud gets positively charged while the earth underneath gets charged positively as a reaction.<\/p>\n

As factors such as storm, wind etc. increases, the negative charging in the lower part of the cloud increases and as a result the positive charge in places on earth the cloud impacts also increases. Thus, the potential difference that keeps increasing between the clouds and earth, cuts through the air and causes a discharge between the earth and the clouds through a conductor duct in the form of cracks like the branches of a tree. If this discharge and interaction occurs between clouds, it is called a lightning bolt. However, if this discharge occurs between the earth and clouds, it is called a lighting strike.<\/p>\n
