minus-squareJPAKx4linkfedilinkarrow-up2·4 months agoAh, so that’s why it’s half power compared to DC, makes sense.
minus-squarePher@lemmy.worldlinkfedilinkarrow-up2·4 months agoKinda, it’s half the power because the power goes like the temporal average of the current squared, the current oscillates like sine or cosine, and the temporal average of a sine or cosine squared is 1/2.

minus-squareDuamerthrax@lemmy.worldlinkfedilinkarrow-up2·4 months ago Not really. Where on earth would Mains be a square wave?

Low quality UPS Inverter
That’s not what Mains means.
