How did the invention of the lightbulb and advancements in electrical power play a key role in the growth of American cities in the late 1800

Electrical power was key to promote more industrial and cultural development.

Explanation:

The invention of lightbulb and mainly the use of electrical power was essential to boost the growth of Ametican cities in the late 1800. For one side, lightbulb was used to put lights on the street improving security and also to fabricate luminous banners for theathers, cinemas, restaurants and more. Cities like New York City and Las Vegas would not be the same without the invention of lightbulb. On the other hand, electricity started very slow at the industry, but eventually Direct Current (DC) electricity started to be used in different parts of the United States promoted by Thomas Edinson which boosted the use of elctrical energy by local and industrial sectors. The Electricity inclsuion reached its peak with the promotion of Alternating Current (AC) promoted by Nicola Tesla and Westinghouse Electric.

The invention of the light bulb and advancements in electrical power played a key role in the growth of American cities in the late 18000s because they allowed factories to produce more, which required more workers to move to the cities.
