From whom does Edison perceive the most significant threat to his electrical ventures?

• A. Henry Ford
• B. Nicola Tesla
• C. J.P. Morgan
• D. Alexander Graham Bell

Answer: (B)

Edison's most significant threat in his electrical ventures is perceived to be Nikola Tesla. Their rivalry stems from different approaches to electrical systems, particularly the battle between Edison's direct current (DC) and Tesla's alternating current (AC). Tesla's innovation and the efficiency of AC power transmission posed a significant challenge to Edison's methods and business model.

Tesla's ideas were revolutionary, and as he developed AC technology, it became clear that his system had advantages over Edison's DC system, including the ability to transmit electricity over long distances more efficiently and with less energy loss. This innovation not only threatened Edison's market share but also positioned Tesla as a formidable competitor who could disrupt Edison's established electrical empire.

The other figures mentioned—Henry Ford, J.P. Morgan, and Alexander Graham Bell—while influential in their own rights, did not pose the same direct threat to Edison's electrical business as Tesla did. Ford focused on automotive innovations, Morgan was more involved in finance and investment rather than direct competition in electrical systems, and Bell was more aligned with communications technology, which did not directly challenge Edison's electrical endeavors in the same way.
