How did Thomas Edison make the first light bulb?

Answer 1

he woked on it for 15 years. He first made a airless glass that has the shape of a sphere and then he put in a filament (string that powers the light bulb) which was made out of carbon and powered the lightbulb through electricity

Answer 2

Thomas Edison didn't invent the first light bulb, but he did create the first commercially practical incandescent light bulb in 1879. He experimented with various materials for the filament and eventually settled on carbonized bamboo as it lasted longer and provided a steady source of light. Edison's light bulb design, along with improvements in the electrical grid, revolutionized the way we illuminate our world.
