This is one of my favorite logic puzzles!?!


Question: This is one of my favorite logic puzzles!!?
(Edit: it is more a practical than a logic puzzle)!.
Imagine you are in a room with 3 switches!. In an adjacent room there are 3 bulbs (Edit: let's say in lamps which are on a regular table) - all are off at the moment, each switch belongs to one bulb!. It is impossible to see from one room to another!. How can you find out which switch belongs to which bulb, if you may enter the room with the bulbs only once!?Www@Enter-QA@Com


Answers:
Turn two of them on!. Wait a few moments!. Then turn one off again!.
Enter the room with the bulbs!.
The one that is on is clearly the one you switched on and left on!.
Feel the others!.
The one that is warm, but off was the one you switched on for a few moments and turned off again!.
The one that is cold is the switch you never flipped on!.Www@Enter-QA@Com

first u switch one switch, and leave it on for a while, like 10 minutes, then turn it off!.
then pick anothe switch and turn it on, and leave it on!.
proceed into the room!.
the light of the first switch should still be hot from when u turned it on so it will belong to that switch!.
the light that is on belongs to the switch u left on!.
the remaining light belongs to the switch u didn't touch!.Www@Enter-QA@Com
