In the basement there are 3 light switches in the off position. Each switch controls 1 of 3 light bulbs on the floor above. You may move any of the switches, but you may only go up stairs one time. How can you determine which switch controls each light?
You can olny use one switch at a time....but all seperately if you want too

we have S1, S2, And S3.
Turn S1 on for 5 minutes.
Turn it off. Then turn S2 on.
Go upstair. S2 controls the "ON" light bulb there. The other two is off. Feel the next light bulb, if it is hot, S1 controls it. If it not, S3 controls it.

turn 2 on for a minute, then turn 1 of 2 off, then see which one is hot.
1 light will be on, that is the switch you left on.
1 light will be hot, but off, that is the 2nd switch you turned on & off later.
1 light will be cool & dark, making it switch #3

Turn 1 on until you think the bulb has warmed up, turn it off and turn 2 on. Go down stairs and :
1 is the warm bulb
2 is the lit bulb
3 is the cold bulb
