key term - Benjamin Franklin's Kite Experiment

Definition

Benjamin Franklin's Kite Experiment was a groundbreaking demonstration conducted in 1752 to prove that lightning is a form of electricity. Franklin flew a kite during a thunderstorm, using a metal key attached to the string to draw electrical charge from the atmosphere, which led to significant advancements in understanding electricity and magnetism during the 18th century.
