  • How It Works: When electricity passes through a filament or gas in the bulb, it produces light. This process is known as incandescence or gas discharge.
  • Safety or Efficiency Tip: Using energy-efficient bulbs like LEDs can save electricity and reduce fire risks due to less heat produced.
  • Examples We See Around Us: LED bulbs in ceiling lights, table lamps, and streetlights.
  • Fun Fact: The first practical light bulb was invented in 1879 by Thomas Edison, which revolutionised how we light our homes.

Toasters

  • Everyday Use: Toasters help us make crispy toast quickly, perfect for breakfast or snacks.
  • How It Works: When you place bread in the toaster and set the timer, electric coils heat up and brown the bread.
  • Safety or Efficiency Tip: Toasters often have automatic shutoff features to prevent overheating.
