Basement Attic Light Switch Riddle

Then switch 1 would be the switch.

Basement attic light switch riddle.

One of them controls a lamp in the attic and two of them do nothing. There is no one there to help you. There are three light switches outside a room. You must determine which needs saving and remove the other two.

Flip a second switch and run up to the attic. There are three switches in the basement two of which are useless one is connected to a lightbulb in the attic. Switch 3 on 5 minutes then off. You need to determine which switch operates the bulb.

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 3 switches downstairs each corresponding to one of the light bulbs upstairs. As long as you don t stop for a beer before running up the light that s off but warm to the touch is the first switch. However you know the light is off to start.

There are three light bulbs in your attic. 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. The light on is the second and the light off is the switch you didn t flip. The door is closed and you cannot see if the light is on or off through the door.

Turn on one switch for five minutes then turn it off. You are in a basement with three light. Outside of the closet there are three light switches. Test your brain logic by trying to solve this real life situation riddle.

All of them are turned off and their switches are installed downstairs. I was thinking about the light switches. You have no way to see into the attic or to see reflected light from the attic. Inside is a single light bulb controlled by one of the three switches.

How can you figure out which light switch goes to which light bulb by only making 1 trip upstairs. If you go upstairs to the attic you are not allowed to return to basement. Go upstairs and touch the bulb. The door to the room is closed and there are no windows.

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. The famous light bulb riddle. It s basically the same solution as our first idea.

How can you find out which switch to which bulb corresponds. If the bulb is cold.
