Lightbulb In The Attic Question

There is a lightbulb inside a closet.

Lightbulb in the attic question.

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. The hazard of a keyless in an attic if one exists is the physical placement of the fixture and requisite lamp. This is one of my favorite logic puzzles with a real life solution. This will tell us that the switch which is in an off position corresponds to the light bulb that s off in the attic.

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. If we have 2 of the switches on then when we go into the attic 2 of the light bulbs will be on. Outside of the closet there. Each corresponds to one of the three light bulbs in the attic.

You can play with the switches as much as you want and after that you can visit the attic above just once. How can you find out which switch to which bulb corresponds. However you know the light is off to start. There are three switches in the basement two of which are useless one is connected to a lightbulb in the attic.

And if we have 1 switch on and the other 2 off then we know which switch corresponds to the light bulb that s 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. There are three switches downstairs. The door is closed and you cannot see if the light is on or off through the door.

There are three light bulbs in your attic. Question for you guys. You can turn the switches on and off and leave them in any position. You must determine which needs saving and remove the other two.
