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?

Turn 2 lights on. Wait 5 minutes. Turn one of them off. Then go up and see which light is still on, which is off but still hot, and which is cool.

My brother just moved into a new house. He wasn't sure where he wanted outlets in one room, and the drywallers and painters were coming soon. So he instructed the electrician to wire up a box along every other stud at a predetermined height. After the walls had been painted, he located one of the boxes, cut the wall, and installed an outlet. It didn't work. He located another box pulled the wires through and that one didn't work as well. He contacted the electrician, only to find out he had wired them all in a circuit like old time Christmas bulbs. In order for them to work, a working appliance would have to be plugged into every box and turned on.
Sounds like the same electrician in the above puzzle.
