Detailed explanation-1: -Edison invented or refined devices that made a profound impact on how people lived. The most famous of his inventions was the incandescent light bulb (1878), which would revolutionize indoor lighting and forever separate light from fire.
Detailed explanation-2: -Edison developed direct current–current that runs continually in a single direction, like in a battery or a fuel cell. During the early years of electricity, direct current (shorthanded as DC) was the standard in the U.S. But there was one problem. Direct current is not easily converted to higher or lower voltages.
Detailed explanation-3: -Electrified tools boosted industrial productivity, and many were eventually made available to domestic “do-it-yourselfers.” Electric power for transportation made subways practical and streetcars more efficient. These in turn provided central stations with daytime consumers of electricity.
Detailed explanation-4: -The film explained that the major challenge for Edison’s DC electricity was that it couldn’t be transmitted long distances. As a result, Edison’s system required a power plant every mile or so.
