Nikola Tesla’s polyphase AC system is primarily applied to which major modern electrical function?

💡 Explanation:

The polyphase Alternating Current (AC) system, pioneered by Nikola Tesla, is the foundation of the modern electrical grid. Its major applications stem from AC's ability to be easily converted to high voltage via transformers for efficient, long-distance transmission, minimizing energy loss. The system also includes the AC induction motor, which powers most large industrial machinery and appliances, making high-voltage transmission and power motors the primary functional application of his work. The other options are typically associated with Direct Current (DC) power or specialized applications.
