Will a blown fuse prevent lights from turning on?
Will a blown fuse prevent lights from turning on? My kitchen light is working but all other lights in house won’t turn on. The power is working fine and everything else is working apart from the lights. I’ve tried using a new light bulb just in case it might have been a blown bulb but it still didn’t work. Please help! Would like to know before I call an electrician.
Fuse Box Question?
Additional details in response to below comments: There is a label inside the box that states 30 Amp, and 125-250 volt. (I am going by memory, since I am not at this place right now). Inside the box itself are four separate slots for fuses. Two are 20 amps, and the other two are 30 amps. The wall a/c has its own separate fuse slot. I haven't yet figured out what the other 3 slots bring power to. My biggest overload concerns are the computer setup (CPU, monitor, cable modem, printer, and various charging cords for cell phone and iPod), and the TV entertainment center. My fridge is newer, so it hopefully won't be a power hog, and the stove is gas. FWIW, I've never tripped a circuit breaker in my apartment.
Which bulb will fuse 20w or 25w when connected in a series to a voltage 220 volt?
Good question.Badly written however.If I am to loosely translate what you are trying to ask.What [light bulb-incandescent] will burn out first, a 20W or a 25W bulb designed for 220 volt operation, with some sort of load?The problem is not which one, but why are they in series?Light bulbs are designed to operate in parallel with the voltge source .the only thing that inhibits them is a switch of some sort, and a fuse at the main distribution panel or circuit breaker panel.So, to answer your question, one needs to know wht is the load that is in series with these lamps?Is it just the lamps at 220 volts , and one wants to know which will light up first? or is it each lamp in series with some load, and how much load would cause a particlular lamp to light up?Add your answers to a comment in the top of the page. perhaps someone can translate from Urdu to English.
Which of the following is the weakest link in an electric circuit?-the switch,the pilot lamp,the fuse or recep
Yes, the fuse, as it is designed to sacrifice itself to save the other parts. However, it is even weaker than you might think if it is a metal-element fuse (vs. a chemical fuse or some other kind). As a fuse operates close to its rating in order that a fairly small increase will blow it, the fuse runs warm, but not up to the melting point. Every time the current is turned on, the element goes from cold to hot, causing the element to physically flex. You can actually see this happening if an open fuse holder is used and the fuse shell is clear glass, of course. And if there is a surge greater than the normal operating current, say due to feeding a cold light bulb, a motor at standstill, etc., the surge will magnify the flexing. Now what happens if you flex metal repeatedly. Yes, the top of an Aloha Airlines 737 blows off! Or in this case the fuse flexes one too many times, fractures and opens up ("blows" would not be apt) and the circuit fails. Thus any fused circuit operating near the fuse's current rating is waiting for a fall, so keep that in mind. If fatigue is the cause, that is one case where replacing the fuse without checking the circuit for faults leading to excessive current is OK. After all, the circuit is not bad, just too old. (Hmmm, sounds like me.)
30 bulbs are connected in series. If one bulb is blown(fused), and 29 bulbs are joined in series and connected to the same supply, will the light in the room increase, decrease, or remain the same?
Caution: This is a SWAG[Scientific Wild Assed Guess][1] answer with not much thought and no research. First I have to assume, from what I’m guessing about the meaning of fused, we’re talking apples and apples. I can come up with three completely different scenarios, but I’ll go with fused as in combined or shorted one side to the other taking out one of the bulbs as suggested by Harry rather than having installed a protective device for example.The problem answering this question is we don’t know the temperature coefficient of the lamp’s filament or even the type of lamp. We’ll assume incandescent lamp which will have a positive temperature coefficient, but I don’t know that number. If the temp coefficient was zero, the current would increase by roughly 3.3% into 3.3% decrease in resistance. Given power is I^2*R and lumens per watt is what I think we’re talking about, the room lighting would get brighter assuming the current load doesn’t just open one of the bulbs - but with this temperature coefficient, I’m not sure because the resistance at temperature is going to go up.Making an assumption, on something I know nothing about, the temp coefficient is not going to completely nullify the increase in current associated with the shorted bulb, and the light in the room will increase by something less than approx. 3.33%. Yes, 3.33%Footnotes[1] Scientific wild-ass guess - Wikipedia
If two bulbs are in a circuit and one of them is a fused bulb, will the second bulb glow or not?
KInd of a wide open question but deserving of a reply as long as we tie up some loose ends.It wasn’t stated in the question, so first let’s assume the bulbs are the same.Also, are they hooked in parallel or series and is the fuse blown or not?In the case of a non-blown fuse and series OR parallel connection, then yes, both will light. In the case of a blown fuse and parallel lamp connection, then the un-fused lamp will light but the fused one will not. In the case of blown fuse and series connection, then neither will light.OR- - -and just to make my point about the wide open nature of the question, is the fuse on the fused bulb hooked in series or parallel with the lamp itself? It may sound silly but these are exactly the kinds of questions that professionals with experience have learned to ask after having seen about everything. =D
What is the meaning of “the bulb is fused��?
OP ”What do you mean by a fused bulb?”Badly worded Indian Quora question.Why? only in India, do they speak of a fused bulb.In Canada, and the USA, they say a ‘blown bulb’ or ‘burnt out bulb’, perhaps its a UK thing too, but generally its the South Continent speakers who say the word ‘fused’ and ‘bulb’ together.So, what do I mean?This is also incorrect , as the question asks what “do you mean”, this implies it is me who is asking the question.Sorry, this is not how it works. You ask the question. You attach the the meaning to the words.A fuse is a different device.These are type Edison based fuses, (Glass-left S-Type Right) so that the circuit was ‘protected’ from over current.Fuse (electrical) - WikipediaThis is where the mis-appropriation of the word ‘fused lamp’ comes from , and is taught at the high school level.The actual result though, is not a ‘fusing’ of the metal of a lamp , as it is the burning out , and a gap forming in the filiament.This is the reason, that traditionally, when the bulb goes, it is at a point where the tungsten has burnt away due to a flaw in the wire. It gets thinner at that one spot, then overheats, then a ‘blue light’ instantly happens for a second, then the lamp is out.Typically, the lamp will burn out, just as the power is being turned on.Merged into question: What is the meaning of “the bulb is fused”?

On a 2004 Infiniti g35 coupe, where's the fuse location for the license plate lights?
talk about not answering your question.... the fuse for the license plate lights are on the drivers side kick panel. it will not be labeled as license plate lights because its circuit is connected with other circuits, just check all the fuses in that area.
