  1. Investigation of the Incandescent Light Bulb Presented by: Raymond Rogers and Michael Shaffer Advised by: Dr. J. Hoffman Special Thanks to: Duane Miller Dr. R. Larivee Dr. F. Senese Dr. Mumper Dr. Soysal

  2. Project Goals To Write a Brief Biography of Thomas Alva Edison To Measure Electrical Characteristics of Modern Incandescent Light Bulbs To Determine and Measure all Important Physical Characteristics of Light Bulbs To Attempt to Recreate the Original Carbon Filament Edison Light Bulb http://antoine.frostburg.edu/phys/edison/

  3. Thomas Alva Edison(1847-1931) Childhood Menlo Park Patents and Inventions The Golden Years http://antoine.frostburg.edu/phys/edison/

  4. Childhood Years • Samuel & Nancy Edison • Home Life • Education • Employment http://antoine.frostburg.edu/phys/edison/

  5. Menlo Park • The “Invention Factory” and the Muckers • The Birth Place of the Practical Light Bulb http://antoine.frostburg.edu/phys/edison/

  6. Patents and Inventions • In His Life, Edison Completed 1093 Patents • Still Holds World Record for Most Patents http://antoine.frostburg.edu/phys/edison/

  7. The Golden Years • Edison, the Workaholic • Died - October 18, 1931 at the age of 84 http://antoine.frostburg.edu/phys/edison/

  8. Analysis of Modern Light Bulbs Specifications of Apparatus Procedure Quantitative Analysis of Data http://antoine.frostburg.edu/phys/edison/

  9. Specifications of Apparatus/Supplies • Variac power supply • Multi-meters • Light Bulb platform • Light Bulbs • Various Accessories http://antoine.frostburg.edu/phys/edison/

  10. Procedures Research / Inquiries Experiment Development Execution of Experiment Example http://antoine.frostburg.edu/phys/edison/

  11. Quantitative Data Analysis Resistance Vs. Power Characteristics of Manufactured Edison Bulb Findings Current Vs. Voltage 1 Current Vs. Voltage 2 Current Vs. Voltage 3 http://antoine.frostburg.edu/phys/edison/

  12. Further Interest • Curiosity in Tungsten Filaments • Up Close and Personal http://antoine.frostburg.edu/phys/edison/

  13. The “Edison” Bulb Research and Development Carbon Experiments Conclusions http://antoine.frostburg.edu/phys/edison/

  14. Research and Development Personnel Consultation Reference Insight of Curiosity…the Pickle http://antoine.frostburg.edu/phys/edison/

  15. Experiments • The Creation and Testing of 78 Carbonized Filaments http://antoine.frostburg.edu/phys/edison/

  16. Explosions in the Lab

  17. Results

  18. Carbon http://antoine.frostburg.edu/phys/edison/

  19. Conclusion What Knowledge Have We Acquired by this Project? The Future of Lighting Where do we go from here? http://antoine.frostburg.edu/phys/edison/
