Basement Attic Light Switch Riddle

One of them controls a lamp in the attic and two of them do nothing.

Basement attic light switch riddle.

There are three light bulbs in your attic. How can you figure out which light switch goes to which light bulb by only making 1 trip upstairs. You need to determine which switch operates the bulb. There is no one there to help you.

I was thinking about the light switches. You can turn the switches on and off as many times as you wish they are all off to begin with but may only enter the room once. Turn on one switch for five minutes then turn it off. If you have 3 switches downstairs have a time delay of 5 minutes between each switch.

Switch 1 leave on 5 minutes then shut off. You must determine which needs saving and remove the other two. The door to the room is closed and there are no windows. Go upstairs and touch the bulb.

Test your brain logic by trying to solve this real life situation riddle. You are in the basement of a house where there are are three identical on off switches. However you know the light is off to start. You can play with the switches as much as you want and after that you can visit the attic above just once.

Inside is a single light bulb controlled by one of the three switches. The light on is the second and the light off is the switch you didn t flip. If the bulb is cold. You have no way to see into the attic or to see reflected light from the attic.

The door is closed and you cannot see if the light is on or off through the door. You are in a basement with three light. All of them are turned off and their switches are installed downstairs. Outside of the closet there are three light switches.

Then switch 1 would be the switch. There are three switches in the basement two of which are useless one is connected to a lightbulb in the attic. How can you find out which switch to which bulb corresponds. There are 3 switches downstairs each corresponding to one of the light bulbs upstairs.

Flip a second switch and run up to the attic. There are three light switches outside a room. It s basically the same solution as our first idea. Switch 3 on 5 minutes then off.

The famous light bulb riddle. If you go upstairs to the attic you are not allowed to return to basement.
