Detailed explanation-1: -By conducting the kite experiment Franklin proved that lighting was an electrical discharge and realized that it can be charged over a conductor into the ground providing a safe alternative path and eliminating the risk of deadly fires.
Detailed explanation-2: -Franklin discovered that by linking multiple jars together he could increase the amount of charge they could store. He called this new assembly of Leyden jars a “battery, ” and he is credited as being the first to use the term in relation to electricity.
Detailed explanation-3: -On June 10, 1752, Benjamin Franklin was said to have flown a kite during a thunderstorm to collect ambient electrical charge in a Leyden jar, enabling him to demonstrate the connection between lightning and electricity.
Detailed explanation-4: -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.
