There is a lightbulb inside a closet.
Lightbulb in the attic question.
All of them are turned off and their switches are installed downstairs.
However you know the light is off to start.
You can turn the switches on and off and leave them in any position.
There are three switches in the basement two of which are useless one is connected to a lightbulb in the attic.
Question for you guys.
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.
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.
How can you find out which switch to which bulb corresponds.
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.
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.
There are three light bulbs in your attic.
You must determine which needs saving and remove the other two.
Each corresponds to one of the three light bulbs in the attic.
It s basically the same solution as our first idea.
The hazard of a keyless in an attic if one exists is the physical placement of the fixture and requisite lamp.
There are three switches downstairs.
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.
Now a week later i noticed condensation on one side of the light fixture again but.
This will tell us that the switch which is in an off position corresponds to the light bulb that s off in the attic.
