Which historical figure is associated with experiments in electricity and the invention of the lightning rod?

• A. Benjamin Franklin
• B. Albert Einstein
• C. Thomas Edison
• D. Nikola Tesla

Answer: (A)

The main idea here is linking early electricity experiments to a practical device that protects structures from lightning. Benjamin Franklin conducted famous work in the 18th century showing that lightning is a form of electricity, most famously through the kite and key experiment. He also proposed and demonstrated a protective device—a metal rod attached to buildings and grounded to direct the electrical discharge safely into the ground. This is the lightning rod, a simple yet essential safety measure grounded in his observations about how electricity travels. While Albert Einstein, Thomas Edison, and Nikola Tesla all made monumental contributions to electricity and its applications, Franklin is the one most closely tied to both initiating practical electricity experiments and inventing the lightning rod to prevent fire from lightning strikes.
