How did the light bulb work in the industrial revolution?
Working independently, they found that passing a current through a fine carbon filament could produce light. The filament had to be held in a vacuum to prevent oxidation of the carbon, so they provided an evacuated glass bulb.
How did the light bulb affect industrialization?
One of the most notable impacts of the light bulb was that it made longer work hours possible. While a longer work week often meant abuse of the working class, increased nighttime productivity helped spur industrial advancements.
