Discovery of Electricity:
Franklin conducted a series of experiments in the mid-1700s to understand the nature of electricity. His most famous experiment was the kite experiment in June 1752, where he flew a kite during a thunderstorm and attached a metal key to the kite string. When lightning struck the kite, electricity traveled down the string, causing a spark and charging a nearby metal jar. This experiment provided evidence that lightning was a form of electrical discharge.
Invention of the Lightning Rod:
Based on his understanding of electricity, Franklin invented the lightning rod in 1752. A lightning rod is a metal rod installed on top of a structure and connected to the ground. When lightning strikes the rod, it provides a path of least resistance for the electricity to travel safely into the ground, reducing the risk of damage to the structure. Franklin's invention significantly improved building safety during thunderstorms.
While Franklin made significant contributions to the understanding of electricity and invented the lightning rod, it's important to recognize that other scientists and researchers also played roles in advancing the field of electricity. However, Franklin's experiments and inventions were crucial in popularizing the study of electricity and its practical applications. His work laid the foundation for further advancements in electrical science and technology.
