minus-squareJPAKx4@lemmy.blahaj.zonelinkfedilinkarrow-up0·24 days agoAh, so that’s why it’s half power compared to DC, makes sense.
minus-squareulterno@lemmy.kde.sociallinkfedilinkEnglisharrow-up0·24 days agoUnless the AC is a square wave, in which case stuff becomes different.
minus-squareDuamerthrax@lemmy.worldlinkfedilinkarrow-up0·24 days ago Not really. Where on earth would Mains be a square wave?
minus-squareulterno@lemmy.kde.sociallinkfedilinkEnglisharrow-up0·24 days agoAs far as the appliance cares, it is the only input power it gets at that time.
minus-squarePher@lemmy.worldlinkfedilinkarrow-up0·24 days 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.

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