25 KV AC is more efficient for railways due to lower energy losses over long distances.
25 KV AC is more efficient for long distance transmission as it experiences lower energy losses compared to 750V DC.
25 KV AC allows for higher speeds and heavier loads on the railway system.
25 KV AC is the standard voltage used in many modern railway systems around the world, such as in Europe and parts of Asia.
750V DC may be more su...
