A Riddle

You are alone in a house with three floors. In the third floor, there is a light bulb. In the basement, there are three switches. One switch turns the lamp in the third floor on and off while the other two switches have no function. You cannot see the third floor from the basement, nor can you see which of the three switches has a function. Your job is to find out which switch is responsible for the light bulb in the third floor. You are allowed to go upstairs only one time.

 

How do you find out which switch turns the light bulb on and off?

Turn on switches 1 and 2, wait a few minutes, then turn off switch 2 before going to the attic. If the bulb is off, but warm, you can conclude that switch 2 is the winner. If the bulb is on, it's switch 1. If the bulb is off, but cold, it's switch 3.
