Why do halogen bulbs flicker on a dimmer?
Halogen bulbs flicker on a dimmer because dimmer switches are designed for use with incandescent bulbs, not halogen bulbs. The electrical properties of halogen bulbs, such as their lower resistance when dimmed, can cause flickering when used with dimmer switches not specifically designed for them. Upgrading to a dimmer switch that is compatible with halogen bulbs can help eliminate the flickering.
On a ground floor home there are three switches connected to 2 bulbs and 1 fan - how do you know which switch is for the fan and which are for the 2 bulbs?
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.

If a chandelier has 5 bulbs how can it be re-wired to switch on separately 3-2 bulbs?
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.
