there is a room with three bulbs and another room with three switches how do you know which switch is for whic

Turn two of the light switches on. Wait a while, and then turn one of them off, then quickly enter the room. One light will be on, one off, and one off but still hot.

Because switches are real, electricity is real, and light bulbs are real. Guess what isn't real, though?

house is AC, lights hooked directly in- AC\nCar battery DC, lights run off battery- DC\nTransformers are AC- AC\nBattery charger run through a rectifier- DC\nElectromagnet (had to look this one up)- either

u can use switchs to power each one at a time but u ll need to place them in a parallel format cause using serial means u have to power the first bulb to be able to light any other ,other than that u can use relays and connect them in a way to have the light going in a sequence

Turn on the first light switch for a while. Then turn it off and turn the third light switch on, then enter the room. If the light is on, it is the third switch. If the light is off and cold, it is the second switch. If the light is off, but warm, it is the first switch.

1,000,001... 1 to hold the light bulb and 1,000,000 to turn the room~~~~lol

Many different types are there. Involving electronic swithes or mechanical. Here is the description of a mechanical type:\n\n1. Take a flashlight that produces very bright light.\n2. Take a table/floor fan.\n3. Place the flashlight towards the fan's blades from behind the fan.\n4. Turn the fan ON.\n\nYou have strobe light. You can change the speed of the blinks by changing the speed of the fan.

I assume the goal is to achieve a specified level of illumination and pattern (uniform perhaps?). Consider the light output of the bulbs and the distance from the area to be illuminated (does the room have high or low ceilings?). Consider the type of bulb and lamp structure as to how much of the bulb output is directed toward the desired area. I'm not aware of any simple formula.

It's called a three way switch.

3.\nOne to change the bulb and two to make cocktails.

did you mean how does a light sensor work?

Your answer is correct, and may be fine for your professor, but for readers who are not already familiar with the problem, both the question and the solution are confusingly worded.  I suggest that in the future, you copy the original question here exactly.\n\n\nI would precede your solution with the following:\n\n\nYou can find the floor in a maximum of 14 attempts.\n\nDrop a bulb from the floors in this order:\n14, 27, 39, 50, 60, 69, 77, 84, 90, 95, 99, 100\n\nIf the bulb breaks, stop and test starting from just above the last floor that it didn't break on, and go up one floor at a time.  If the bulb breaks on the first attempt, resume the test from the first floor.\n\nExamples:\n14 (breaks), 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13\n\n14, 27, 39 (breaks), 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38\n\n14, 27, 39, 50, 60, 69, 77, 84, 90, 95, 99 (breaks), 96, 97, 98\n\n14, 27, 39, 50, 60, 69, 77, 84, 90, 95, 99, 100 (breaks)

you can unscrew a lightbulb

On one can tell lighting is different every time.\nJust like it does not hit the same place two times in a row.

The best way to find out might be simply re-open the door to see if the light IS out!
