Why does AC have less copper loss than DC

[QUOTE="NascentOxygen, post: 5506998, member: 336970"] This is probably in reference to the development of the area-wide power distribution system, in an era when the choice was basically between DC all-the-way or AC all-the-way. Transformers enabled the efficient transmission of AC at high tension followed by a step-down to consumer voltages, whereas there was no equivalent available for efficiently stepping down DC at the power levels involved. Transmitting low tension DC throughout a power network involves cripplingly-high I[SUP]2[/SUP]⋅R losses. [/QUOTE]
