Three switches outside a windowless room.....?

Ask someone!!

Turn the first two switches on and leave them on for 2 minutes. Then turn the second switch off and enter the room after half a minute. Feel the two bulbs that are not lit. The warmer of the two belongs to the second switch, and the one that is not at all warm is of the third switch. The bulb that is on is of the first switch.

Go in the room and attatch a transmitter to the light, go outside and use the receiver on the switches to figure out which line carries the signal. Or just have a friend flick switches for you while your in the room. ;D

When there is order/pattern you can tell which switch is connected to which bulb, as in a hotel.But often, the work is done by an apprentice ( the supervisor having gone for his coffee breaks) who takes delight in making me take the guessing game.Ha! Ha! Hope I've answered your question.

since it is stated that the 'three light bulbs are inside the room' (room which is singular, not rooms) then you can switch any or all of them for the bulb/s to light up...... got it?...

Easy!. Turn one one switch - wait a minute then turn on the second switch and wait 5 seconds.

Then, turn them off and enter the room

The "HOT" bulb belongs to switch one

The "WARM" bulb, switch two

and the "COLD" bulb, switch three

open the door but don't enter the room and work the switches

stick your head in the door,and flip the switches while watching which light goes on for each switch...

you can flip one switch and then leave it on for awile and then shut it off. and flip another and leave it on. and walk in the room. then one thats off and warm is the first on your switched. the one thats on is the one thats on on the outside, and then last switch goes to the one that hasnt been touched.

Can I leave the room's door open?

I would just turn them all on
