minus-squareuneatable@lemmy.worldlinkfedilinkEnglisharrow-up9·1 day agoOh no, I didn’t. Should I draw a graph? Pop out some equations? Let’s say P is the nominal power. When I said “The other half” I meant when the solder iron is not plugged. So: 50% of the time at 4xP 50% of the time at 0… Oh shizzzz, you’re right!
