You turn on two switches wait 5 min. and turn one of the switches off! go in the next room the cold one belongs to the switch you never turned on..the warm one the switch you only left on 5 min and the lite one to the switch that is turned on! you switch on one switch for a few minutes, one for ages, and dont turn the other one on at all. you go through to the other room, the bulb that is warm is operated by the first switch, the roasting hot bulb (that would burn your hand) is operated by the second switch, and the cold bulb is operated by the third switch.
Have someone else go into the other room and talk to each other.
The switches would have to be of a type that could switch out a bulb and at the same time switch in its place a resistor of equivalent value.
All dimmer switches hum. The older they get, the louder the hum. If you have compact florescent bulbs in the fixture, this will cause the switch to hum louder.
120 volt xenon bulbs are fully dimmable just like a regular incandescent bulbs, using regular old 120 volt dimmer switches.
Turn on one light and leave it on for a little while then turn it off. Turn the next light on and open the door. Go up and feel the light bulbs..the warm one is the first loth switch,, the one that is still on is obviously the second light switch and the cold/regular temperature light bulb is the last switch that you didn't touch.
The two bulbs will be wired in parallel with each other. The switch will be wired into the circuit upstream of the bulbs.

To do something like that you would first have to have each light on it's own smart switch. Then you would need a master switch that would control each of the other smart switches. You can find switches like this at www.smarthome.com
Turn switch A on and then wait for a couple minutes. Turn switch A off and switch B on. Go to the attic, one light bulb should be on, that's switch B. Now feel the light bulbs, one should still be warm from having been turned on and then off, that's switch A. The one that's off and cool is switch C.
How did you want to switch on the bulbs? If there isn't a separate circuit already running from the switch, through the wall, and to the chandelier, then you'd have buy pull chain switches. The chandelier would have to have holes drilled to mount the switches. The load wire from the house would be wired to the load side of each switch. Then two bulbs to one switch and three bulbs to the other switch. All the neutrals would tie together to the neutral from the house. I would HIGHLY recommend just purchasing a dimmer switch from your local hardware or home center. You could easily change the switch in the wall to a dimmer switch and have a lot more control over the illumination, and it wouldn't look like you have burned out light bulbs in your fixture. You can rewire a 5-bulb light for a 3-2 switch in a couple of other ways. Remove the light from the ceiling, open the lamp wiring and divide the selected 3 and 3-light sets. All of the neutral wires stay together (usually wired to the screw shell of the lamp holders). Add a 3-way switch in the fixture (e.g., off, 3-on, 5-on, or off, 2-on, 5-on) or bring each group of 3 and 2 hot wires out to separate wall switches. Switch 1 is 2 bulbs, switch 2 is the other 3 bulbs, and switch 1 and 2 together is all 5 bulbs. Or you can put all or some of them on dimmers.

You left out the most important parts of the riddle. The way the questionis worded, all you have to do is turn one switch on, walk over to where thefan and the bulbs are, see which one is on, mark the switch, and do thattwo times.The way the riddle works: The switches are on the ground floor of the house,and the bulbs and the fan are on the 3rd floor. Now, how do you figure outwhich switch controls what, without climbing the stairs more than once ?-- Stand by the switches. Turn 2 of them ON. Wait 15 minutes.Then turn one of the 2 OFF, and turn the 3rd one ON.Then run upstairs and see what you have there.-- Whatever is OFF ... either the fan or 1 bulb ... belongs to the switch that's OFF.Now you only have to associate the 2 remaining switches with the 2 remaining items.-- If 2 bulbs are ON, then they belong to the 2 switches that are ON.One bulb is cool, and the other one is warm.-- If only 1 bulb is ON, then it's either cool or warm.-- A warm bulb that's ON belongs to a switch that was ON for 15 minutesbefore you ran upstairs.-- A cool bulb that's ON belongs to the switch that you turned ONjust before you ran upstairs.You have identified all 3 switches with only one trip up the stairs.

Yes. Most flashlights have a series circuit involving a battery, a switch, and a bulb. More complex variants might have two bulbs in parallel, two or more bulbs on two switches, etc. but the basic principle is a series circuit - turn the switch on and the bulb illuminates.
The easiest solution is to take the bulbs out. If you don't want to do that then a switch in one of the doors may be faulty, or the switch that operates the light independently of the door switches may be permanently in the 'on' position. phil the swithces are trouble prone but cheap and easy i would replace all four they unscrew like a bolt then the wire pulls off they are a few dollars each
