From time to time homeowners of personal houses give thought to how to guard them selves as well as their residence from the lightning strike. In the end, there are regions where by the depth of thunderstorms is from eighty several hours each year.
Bonds be part of metallic roofing parts and grounded constructing programs to the most crucial conductor, preventing lightning from jumping concerning objects.
From his famed experiment using a kite and key to ascertain if lightning was indeed electrical energy Franklin posited that The easiest way to secure a developing from your Threat of lightning was to find a way to place a pointed iron rod at the height in the setting up with a wire working down to a different rod buried into your earth.
