    If lightning strikes a structure, the electricity may cause a fireplace or can electrocute anyone who is nearby. So how can people protect themselves against one of many strongest and many unpredictable forces of nature? A lightning rod, also known as a finial or air terminal, is a simple device that can protect all kinds of structures from electrical damage after a storm.

    What Is It?

    A finial can be a metal rod which is installed on top of a structure or another structure that needs to be protected from lightning, including bridges and ships. They can can be found in many forms in addition to straight rods, including rounded, pointed, or flat. They might be hollow or solid, and will be made up of bristles, such as a brush. Whatever form they are available in, the metal spikes draw the electrical charge from a lightning strike, diverting the vitality by transferring it to the ground by way of a wire attached to the device.

    So how exactly does It Work?

    A straightforward lightning rod depends on three integral pieces – the metal rod, a wire, plus a grounded absorber. If the finial is struck, the electricity naturally travels over the conductive wire, which is consisting of a conductive material, and in a ground. The bottom, also known as an earth, is another little bit of metal that is certainly driven to the actual ground. From here the electricity disperses without causing injury to the structure. However, if homeowners suspect that the rod has been hit, they should still be sure to examine their property for just about any damage since a great deal of energy has been transferred.

    Buildings that require extra protection may use a process consisting of several of these devices that were networked together through bonding conductors, connectors, and supports. The conductors will be linked to the ground within the most direct path, making certain the electricity is shipped away from the building immediately.

    History of the Lightning Rod

    Benjamin Franklin, the United States’ pioneer of electricity, designed the earliest lightning rod. He first came up with the concept in 1749, as well as over another decade, he developed the theory into a usable household product. In fact, early incarnations on this device were known as being a Franklin rod. There’s some evidence that the first lightning rod was adopted with a tower in Russia during the early Eighteenth century, before Benjamin Franklin’s invention, but there’s no concrete proof until this was the goal of the structure.

    Following your use of the finial had become common, people the 19th Century did start to utilize them as decorative accents for houses. These folks were often decorated with glass balls, that had been both attractive and served to alert occupants which a strike had occurred, since the balls would shatter when hit.

    Due to this ingenious device, people is now able to rest comfortably within the electrical storm and enjoy the awesome display of nature’s power without having to worry they are in danger.
