For the same voltage and wire size, transmission losses in DC are the same or lower (due to skin effect and capacitive/inductive losses). They are only higher when comparing low-voltage DC with higher-voltage AC, but the key difference is the voltage, not DC versus AC.
(As a bonus, DC has lower peak voltage for the same RMS voltage, so the wires need less insulation.)
- appletrotter 3y agoSure, but GP and OP are talking about supplying power at the voltages devices (such as LEDs) currently consume. AC is associated with higher voltage in this context even if that isn’t intrinsic.
