Final answer:
OPTION B.
Benjamin Franklin used a kite to collect electricity from the air during a thunderstorm and stored it in a Leyden jar. This experiment helped to demonstrate the connection between lightning and static electricity.
Step-by-step explanation:
During a thunderstorm, Benjamin Franklin attempted to collect electricity from the air using a kite. This famous experiment involved flying a kite during an electrical storm and drawing sparks from a key that was attached to the kite string. The sparks observed were similar to those produced by static electricity, helping to demonstrate a connection between lightning and static electricity. Additionally, Franklin made use of a Leyden jar to store the electric charge collected during his experiments. The Leyden jar acted as an early form of capacitor, consisting of a glass jar with metal foil on the inside and outside, allowing for the storage of a significant amount of electric charge.
