Would we need Alternating Current if superconducting wires existed?
The major advantage of Alternating Current is that it can be transmitted to large distances without significant losses, which is not possible in Direct Current. Had economical superconducting wires existed, DC could be transmitted to any distance without any loss, and DC is much safer compared to AC. So, I want to know, do we need AC if long distance transmission is no longer a problem because of superconducting wires? Would DC be better in that case, or we would still need AC?
