If lightning strikes a structure, the electricity can cause a fireplace or can electrocute anybody who is nearby. But exactly how can people protect themselves against one of the strongest and quite a few unpredictable forces of nature? A lightning rod, also referred to as a finial or air terminal, is an easy device that will protect all sorts of structures from electrical damage after a storm.

What Is It?

A finial can be a metal rod that is mounted on top of a structure or other structure which should be resistant to lightning, including bridges and ships. They can come in many forms besides just straight rods, including rounded, pointed, or flat. They might be hollow or solid, and may be made up of bristles, such as a brush. Whatever form these come in, the metal spikes draw the electrical charge from the lightning strike, diverting the force by transferring it down through a wire attached to the device.

How can It Work?

A simple lightning rod is dependent upon three integral pieces - the metal rod, a wire, along with a grounded absorber. Once the finial is struck, the facility naturally travels down the conductive wire, which is consisting of a conductive material, and in a ground. The ground, also called an earth, is an additional piece of metal that's driven into the actual ground. From this point the facility disperses without causing damage to the structure. However, if homeowners suspect that the rod continues to be hit, they must be likely to examine their home for any damage since quite a lot of energy continues to be transferred.



Buildings that require extra protection might use a process made up of some devices that have been networked together through bonding conductors, connectors, and supports. The conductors are coupled to the ground inside the most direct path, making sure the electricity is distributed out of the building immediately.

Good reputation for the Lightning Rod

Benjamin Franklin, the United States' pioneer of electricity, designed the initial lightning rod. He first developed the concept in 1749, and also over another decade, he developed the concept in to a usable household product. The truth is, early incarnations with this device given assistance as a Franklin rod. There is some evidence that this first lightning rod was applied with a tower in Russia during the early 1700s, before Benjamin Franklin's invention, but there's no concrete proof that this was the purpose of the design.

As soon as the standby time with the finial had become common, people in the 1800s begun to rely on them as decorative accents for homes. These were often decorated with glass balls, that have been both attractive and served to alert occupants that the strike had occurred, as the balls would shatter when hit.

As a result of this ingenious device, people can now rest comfortably throughout an electrical storm and relish the awesome display of nature's power without worrying actually at risk.
