Ok. I was acountless on lemmy for a long time, your comment made me finally register. Thanks!
So, yeah, with double the voltage you get 4x the power. But you you put 4 times the power at 50% of the time, you get only 2x the power. And the other half of the time, you get 0 power. On the average you get the same power output.
You double counted there.
You said 4x power 50% of the time and then said “the other half of the time.”
So you’re calculating 50% of 50% which is 25% duty cycle.
Oh 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!
Oh man I was going through it in my head too...
