Lightbulb In The Attic Question

You can play with the switches as much as you want and after that you can visit the attic above just once.

Lightbulb in the attic question.

You can turn the switches on and off and leave them in any position. There are three light bulbs in your attic. It s basically the same solution as our first idea. The door is closed and you cannot see if the light is on or off through the door.

Now a week later i noticed condensation on one side of the light fixture again but. That is switch on 1 2 wait a minute switch off two and go to the attic and check if the bulb is on hot or cold. All of them are turned off and their switches are installed downstairs. Each corresponds to one of the three light bulbs in the attic.

This will tell us that the switch which is in an off position corresponds to the light bulb that s off in the attic. If we have 2 of the switches on then when we go into the attic 2 of the light bulbs will be on. So a week ago a lightbulb went out in a ceiling fixture that is in closed i go to change it i notice a little bit of moisture at the bottom but nothing else around the fixture is wet at all. The hazard of a keyless in an attic if one exists is the physical placement of the fixture and requisite lamp.

How can you find out which switch to which bulb corresponds. If it s right above a scuttle hole such as you would bump it when you boost yourself up and in then it s in a bad spot. Question for you guys. Outside of the closet there.

This is one of my favorite logic puzzles with a real life solution. There is a lightbulb inside a closet. You must determine which needs saving and remove the other two. However you know the light is off to start.
