Why did Edison make a propaganda campaign against alternating current?

• A. to prevent a negative association with electricity in general
• B. to promote the use of direct current exclusively
• C. to discredit all electrical research
• D. to boost his own profits

Answer: (A)

The situation hinges on shaping public perception to influence which electrical system would dominate. Edison invested in direct current and faced a rival system (alternating current) that could transmit power over long distances, opening the door to widespread electric grids and more customers. To protect his own business, he mounted a propaganda effort that framed alternating current as dangerous. By steering the public to associate electricity with risk, he aimed to keep electricity’s adoption from being hindered by fear, effectively preserving support for electrical power in general—even if that power would be delivered primarily through his preferred method. So the idea is that the propaganda was about preventing a broad negative view of electricity itself, not just discrediting a single technology or pushing one method for profit in isolation. The other options don’t capture that broad perceptual goal: it wasn’t about discrediting all research, nor was it simply to boost profits, and it wasn’t merely a straightforward push for direct current as the exclusive solution.
