Short or overloading of the circuit. The fuse protects the wiring and not the component. Different fuses can handle different loads. For instance a 15 amp fuse can handle a 15 amp load. Add more than 15 amps to the circuit and the fuse will blow. Of course if there is a short in the circuit then the fuse will blow. Replace a 15 amp fuse with a 20 amp fuse and the wiring is no longer protected as it should be and this may cause a fire. Replace it with a 10 amp and it will blow due to the 15 amp load. Always replace a fuse with the exact same size fuse you removed.
Answer 2Answer 1 is correct and I only add additional information to enhance your understanding.
An overloaded circuit is one in which the electrical devices/appliances in the circuit use more current [measured in Amps] than the conductor [wire] is capable of safely carrying.
A short circuit is a condition where a "hot" [electrically energized] conductor [wire] carrying current from the power source [battery for example] somehow comes into contact with a ground wire OR any grounded material [like a car's frame, or sheet metal]. In a short circuit condition, almost unlimited current [Amps] flows, making it a "super" overloaded condition.
Fuses That "Blow"
Fuses [and Circuit Breakers] are safety devices designed and installed in electrical circuits TO PROTECT the conductors [wires] from short circuits and overload conditions which can cause extreme overheating that can result in damage to the insulation and the conductors. And worse the possibility of a FIRE which could destroy the vehicle, house, or other structure in which the circuit is located.
When a fuse [and replacement fuses or Circuit Breakers] "blow," especially if it happens repeatedly, is an indication of an UNSAFE CONDITION in that circuit, usually a short.
The proper "fix" is for a qualified technician, who knows what he/she is doing, to troubleshoot the circuit, find and identify the defect, and make proper repair [s], BEFORE replacing the fuse again [with the properly sized fuse or circuit breaker].
Some ignorant few will suggest installing a larger fuse or breaker to solve the problem, BUT that will only amplify the problem, not solve it. Do not follow "bad" advice and install a larger fuse in a misguided attempt to correct the problem. To install a larger fuse would almost guarantee damage to the wiring and an electrical system fire.

What burns a fuse in Ford Bantam?
A short to ground or an overloaded circuit will blow a fuse.
What happens when a fuse burns out when overloaded with too many appliances?
the circuit is broken.
What burns the fuse?
Too much current, electrons, going through the fuse heats it up till it melts and there is no longer a way for the electricity to go through the fuse.
What are the uses FUSE?
They are a safety feature in the case of an energy surge - without the fuse damage could be dome to the appliance, with the fuse if their is a surge of electricity it burns out the fuse so can't travel all the way to the appliance damaging it.

Where is the fuse for an 2007 Impala rear defrost?
There is no fuse, it is directly connected and when it burns out it destroys the wire harness. Found this out the hard way on my 07 Impala.
How do you fix the problem of the brake lights fuse burns?
You need to find the short circuit in the wiring.

You have a short to ground in that circuit.
If a freeway mini bike's wires to the fuse came loose and you tried to solder the wires back on but cracked the fuse holer and so you solderd them strait to the fuse Is this Okay?
AnswerNO. What will you do when the fuse burns out?That fuse holder was designed into the system for a good reason, to make it simple to replace a burned out fuse. Now you have made it much harder to do a simple repair job.Answeryes because even if the fuse burns out again alls u gotta do is desolder it then sodder a new fuse in. also i would add more wire because that old wire mite not survive a lot of soldering and desoldering and bending
Why are fuses used for protection of resistive loads?
Fuses actually have a lower resistance that the wire or carrier that is carrying current to and from the fuse. The purpose of a fuse is so that it will burn out before the carrier burns out. When a fuse burns out it breaks the current and therefore no more electricity can pass through it until the fuse is replaced. You gauge the fuse for a little more current than you normally have traveling through the wire. If a power surge of electricity comes through the wire the fuse will burn out instead of damaging the electrical device that is plugged into or wired into the carrier.
