Tekst Storyboardowy

  • Thomas Edison
  • Thomas Edison invented the Lightbulb
  • Before light bulbs people used candles, but candles were messy and dripped constantly. Candles also did not provide as much light as light bulbs did.
  • Thomas Edison realized that the problem with Swan's design was the filament. A thin filament with high electrical resistance would make a lamp practical because it would require only a little current to make it glow.
  • Almost got it.
  • Light bulbs are used to provide light in areas.
  • Light bulbs were helpful because they were less messy and could provide to larger areas than a candle did.
  • The electric light bulb has been called the most important invention since man-made fire. The light bulb helped to establish social order after sundown, extended the workday well into the night, and allowed us to navigate and travel safely in the dark. Without the light bulb, there would be no nightlife.
  • Helpful Impacts
  • The light bulb impacted our society in a negative way because it affected global warming. If the power station is a coal or oil fuel plant, that plant releases CO2. So to prevent that use a better light bulb like a compact fluorescent instead of an incandescent light bulb.
