HBH Logical 5: 3 Fuses
Hellbound Hackers’ fifth logical challenge is called “3 fuses”.
After a hurricane, you notice that your lights will not turn on… The switches wont work so you go down to the basement to check the fuse box. You notice that 3 fuses are off. If you can only take one trip upstairs to check if the fuse you selected worked, how do you determine whether fuse a, b, or c is the right fuse to turn on your lights?
This one really requires some thinking outside of the box. Pretty much anyone can deduce that it is impossible to solve this puzzle by only turning on one fuse (unless that’s the working one).
I find it very difficult to give any sort of clues to this kind of problem, and therefore the solution will be a bit straight-forward.
You must first turn one fuse on for a while. After this, switch it off and turn another one on. Now, go up the stairs. If the lights are on, the fuse that is switched on is the right one. If not, touch the lights. If they are warm, it was the first switch, because the lights were heated up. In the case that they are cold, the last fuse, which you didn’t touch, was the correct one.

hans: It’s been a while since I last used HBH. I tried to log in now to check my score, but found that I had been banned and was redirected to the very immature “/ban”. Anyway, my username was Joti.
