Why won't it light up? I see a path from the - to the +!
There will be no effective voltage setup across the light.minimario said:Homework Statement

why will it explode?berkeman said:It's a trick question. Once the battery explodes and catches on fire, there will be nothing to power the light...
@minimario -- Why will the battery explode? (That's a hint for the answer for this question...)
minimario said:What you are talking about?
Are you saying that you don't know how to connect wires from the terminals of a battery to the terminals of a light bulb to make the light bulb light up?minimario said:I don't know how they are normally connected :/ (Should be positive to negative, or wat)
Excellent. But in your picture, both wires from the battery are connected to the same terminal of the light bulb.minimario said:Connect one to the positive side, and one to the negative side
Because, in the scenario for your problem, someone connected them incorrectly. Do you think that, if the wires from the battery were connected in the manner shown in the figure, the light bulb will light?minimario said:Why are both wires connected to the same terminal?
PM?berkeman said:Let the OP answer first. It's his/her schoolwork question...
The drawing is unclear, unfortunately. This makes it ambiguous. You (and I) are seeing it differently to how the artist intended.minimario said:

berkeman said:Draw a simple schematic to represent how the clipleads are connected between the 2 terminals of the battery and the 2 terminals of the light bulb. How should they normally be connected? How are they connected in the drawing?

When I looked at the pencil sketch, I saw two wires headed for a light bulb. One of the wires has been extended by clipping it to a third wire so it's long enough to reach the bulb's far terminal.DaveC426913 said:Really? Where is there ambiguity?

The crucial confused connection is cunningly colour camouflaged! Light yellow on a paper-white background does not for a clear image make.
It's an example of those cases where I'm tempted to grade the examiner, rather than the hapess student facing this poor excuse for a diagram.DaveC426913 said:Curioser and curioser. I see no pencil sketch. I see a realistic, CG diagram. It has three yellow wires.
I was going to guess that the original image in post #1 was updated after you examined it, but post 1 and its diagram are quoted in post 2, so, unless someone updated BOTH post images, that doesn't make sense.
There could be several reasons why your lightbulb isn't turning on. It could be a problem with the electrical circuit, a faulty socket, or a burnt out bulb. It's best to check these things first before assuming there is a larger issue.
Yes, lightbulbs can sometimes stop working without any warning. This is usually due to a filament inside the bulb burning out, or a faulty connection. However, if you notice multiple bulbs in your home frequently burning out, it could be a sign of a larger electrical issue.
The most obvious sign of a burnt out lightbulb is when it doesn't turn on. However, you can also check the filament inside the bulb. If it appears broken or discolored, it is likely burnt out. You can also try replacing the bulb with a new one to see if that solves the issue.
Yes, using a lightbulb with the wrong wattage can cause it not to turn on. This is because the wattage determines the amount of electricity needed to power the bulb. Using a bulb with a higher wattage than recommended can cause it to burn out quickly, while using a lower wattage can cause it not to turn on at all.
If you have tried different solutions such as replacing the bulb, checking the circuit and socket, and using the correct wattage, and the light still won't turn on, it could be a sign of a larger electrical issue. It's best to consult a professional electrician to properly diagnose and fix the problem.
