Lightning is the phenomenon which accompanies the discharge of atmospheric charges from cloud to cloud or from cloud to earth. As lightning seeks the path of least resistance, it naturally tends to follow the shortest course between cloud and earth, such as buildings or towering projections. As illustrated, positive electrical charges gather in the clouds and negative charges gather in the ground. When the attraction between these two charges is strong enough they come together in the form of lightning. Lightning rod equipment, properly manufactured and installed, dissipates these charges. |
