Question

Based on details from "Thomas Edison: The Master of Improvement,” how did Joseph Swan and Thomas Edison differ?

Answer 1

Answer:

Joseph Swan experimented using carbon paper filaments, while Edison used metallic filaments initially.

Swan received a formal education, while Edison did not.

Explanation:

• In 1850, Swan started working on a lamp by using a carbonized paper filament.
• He used the evacuated glass tube and after ten years, was able to present his work in 1860. However, the bulb had a short life span but it had good efficiency in working.
• Edison was also experimenting with metallic filament but it took him a lot of energy and attempts to make an ideal filament.
