Which Serbian-American inventor is primarily credited with developing the alternating current (AC) electrical system, including key components like the AC induction motor, which made long-distance power transmission practical?

💡 Explanation:

Nikola Tesla fundamentally developed the polyphase alternating current (AC) system. His designs for the AC induction motor and transformers proved far more efficient for transmitting electricity over long distances compared to Thomas Edison's direct current (DC) system.
