Which inventor is known for creating the technology behind alternating current?

Nikola Tesla is recognized for developing the technology behind alternating current (AC), which revolutionized the way electricity is distributed and used. His work in the late 19th century introduced the concept of using alternating current instead of direct current (DC), which was promoted by Thomas Edison. Tesla's innovations included the design of the AC induction motor and transformer, which made it possible to transmit electricity over long distances efficiently. This had a significant impact on electrical engineering and laid the foundation for the modern electrical grid, allowing for widespread distribution of electricity to homes and businesses. Tesla's advancements were crucial in enabling the use of AC for energy transmission, which ultimately became the standard globally.
