minus-square@JPAKx4@lemmy.blahaj.zonelinkfedilink2•25 days agoAh, so that’s why it’s half power compared to DC, makes sense.
minus-square@Pher@lemmy.worldlinkfedilink2•25 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.
minus-square@ulternolinkEnglish0•25 days agoUnless the AC is a square wave, in which case stuff becomes different.
minus-square@Duamerthrax@lemmy.worldlinkfedilink2•25 days ago Not really. Where on earth would Mains be a square wave?
minus-square@ulternolinkEnglish0•25 days agoAs far as the appliance cares, it is the only input power it gets at that time.

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