Question

the main advantage of AC power transmission over dc power transmission over long distance​

Answer 1

Answer:

Higher voltage is more efficient for transmitting power over long distances (it minimizes the current, and thus the size of the conductors). With AC distribution, high voltage can easily be produced from lower voltages by a transformer, and transformers can be very efficient.
