I connected the small copper wire and the light to a 9V battery, the light came on, but when I changed to the large copper wire, the light did not light up.
Conductor Cross Section: Small vs Large Copper Wire in 9V Battery Experiment

In a 9V battery experiment, a small copper wire successfully lit a light, while a larger copper wire did not. The issue may stem from the larger wire being insulated with a lacquer coating, which could prevent electrical conductivity. Participants suggested scraping the surface of the large wire to remove any potential insulation. Testing this solution could determine if the wire is indeed the problem. Further investigation is needed to confirm the cause of the issue.
