Displaying my ignorance again, a question about microwaving food:
We have a Tesco Curry For Two, for tea. Two cartons of curry; each
takes 5 mins to microwave. If we stack one on top of the other, do we
do them for five mins, or ten mins?
Most/many microwave ovens give out less heat the longer they cook so I
doubt if it is less than double the time. It depends on how well the
cooling of the electronics works.
Stacking them will be a problem as one of them might absorb more energy
than the other. Swapping them over halfway might help.
Yes, its best to check the stuff is hot before you eat it.
Can you cite and article that backs this up?
I doubt it very much but happy to be proven wrong.
My microwave has a heavy transformer and the only electronic components
are a diode and a capacitor, excluding the magnetron of course.
If its not got much electronics then it probably uses a bimetallic strip
and heater to vary the power by switching on and off, when they are used
for a long time the whole thing gets hotter so they spend more time off
than they do when cold at the beginning.
So what you are now saying is that if I use 100% power, as indeed I do
when cooking and not defrosting, the power output is constant.
I thought your earlier post was nonsense, now you have confirmed it.
Do you ever get anything right?
You've admitted the reduction in power is from your bimetallic timer?
Do you accept that the timer would be effectively inoperative for 100%
power for most microwave use?
Is this beyond your limit of understanding?

r, do we
They do. The transformer & magnetron are air cooled, and that nearly 50% of
power input is blown into the cooking cavity as heat. However it doesn't h
ave a lot of effect compared to the microwave energy, as little of it is ab
sorbed by the food. And fwliw the amount of heat given out increases with c
ooking time as the transformer gets ever hotter.

Not so simple as just double. Just microwave them, until they are both
good and hot. I tend towards doing things with multiples of sessions,
adding up to around the stated time, with a stir in between. Microwaves
don't penetrate deeply into food, so the outer gets more heat. A rest
and a stir, helps.
Cooking two of the same, as you are doing - I would cook 1 for 2.5,
then 2 for 2.5, then 1 for 2.5, the 2 for 2.5 minutes. That way they
both end up hot at the same time..

Its obvious to him that if he insults someone then everyone knows he is
He must have thin rolls to heat up the centre before it conducts to the
outside, even if bread is a poor conductor of heat.
Its always the centre that's still frozen when I heat up a bread roll on
1000W. Not so if I set it to 180W for longer.
