minus-square@[email protected]linkfedilink2•25 days agoAh, so that’s why it’s half power compared to DC, makes sense.
minus-square@Pherlink2•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.

Not really.
Where on earth would Mains be a square wave?
Low quality UPS Inverter
That’s not what Mains means.
