Invented the lightning rod
|
Detailed explanation-1: -By 1750, in addition to wanting to prove that lightning was electricity, Franklin began to think about protecting people, buildings, and other structures from lightning. This grew into his idea for the lightning rod. Franklin described an iron rod about 8 or 10 feet long that was sharpened to a point at the end.
Detailed explanation-2: -Being aware of the immense danger of lightening from there, he was able to invent the lightening rod. On May 10, 1752, Thomas-François Dalibard of France conducted Franklin’s experiment using a 12 m iron rod instead of a kite, and he extracted electrical sparks from a cloud.
Detailed explanation-3: -Lightning rods (and the accompanying protection system) are designed to protect a house or building from a direct lightning strike and, in particular, a lightning-initiated fire.
