Who discovered he advantages of AC over DC?

The advantages of alternating current (AC) over direct current (DC) were primarily championed by Nikola Tesla in the late 19th century. Tesla's work on AC systems, including the development of the induction motor and transformer, demonstrated its efficiency for long-distance electricity transmission. His ideas were crucial in the "War of Currents," where AC ultimately became the dominant form of electrical power distribution, largely due to its ability to be easily transformed to different voltages.
