it has a high melting point because it does not melt until and unless the amp goes above 15( which is its bearing capacity )and getting 15 amp is impossible.It is only found in nueclear power plants

∙ 9y agoFuse wires have a low melting point so that if a large amount of current is passed through it to any appliance than that wire would melt and stop the appliance from getting damaged by not letting the current pass any further.

What is the difference between fuse wire and normal wire?
Fuse wire is designed to open under over current conditions. Just like a fuse.
Can solids change shape?
Yes. A solid can change shape. The process is called melting. Each solid has a melting point. Ice has a melting point of 0 degrees Celcius. You should learn this when you are in Grade 6 or 7. But let me tell you 1 thing, some solids like wood do not melt, wood burns when the temperature is too hot. The only type of solids that can melt are the type of solids that have the properties of changing into a liquid. You can search up videos in Youtube for more information about solids. You can type in "Ice melting", that would be a simple thing to start with.add. And solids may have their shape altered by applying an external force. That is how a metal can is formed, or a railway iron, or a copper wire, or a metal spoon. Other solids such as wood and plastic may be similarly deformed.
What is a break in a circuit?
It is a fuse or a breaker. The wire inside the fuse will burn out and will need to be replaced once the fault has be corrected. A breaker is designed to click open, so breaking the circuit.
If You wrap a wire around a piece of iron. If you slowly increase the strength of an electric current flowing through the wire you would expect .?
The temperature of the wire will increase and eventually like the "straw breaking the camel's back" the wire will fail if you apply enough current. It is like exceeding the current in a fuse, the wire essentially disintegrates.
How do you ground a fixture if there is no ground wire from the wall and is it absolutely necessary to use the ground wire from the fixture or can you just cover it?
If you don't have the wire then you just can't ground it. This should not be too much of a problem. Most light fixtures are not grounded and some don't even have ground wires.
Is fuse wire characterized by high resistance and high melting point?
Fuse wire is charaterized by high resistance and low melting point to avoid surge of ac current through it.
Why can't copper wire used as a fuse wire?
Metal with a lower melting point is preferred for fuse wire to reduce the risk of fire.
What is inside a fuse?
There's a thin metal wire with a low melting point inside a fuse.It may be a nichrome wire.However copper wire is not suitable to be the thin wire inside a fuse cause it has a very high melting point.
What are the properties of a fuse wire?
It has high specific resistance and low melting point.........
What is a fuse wire characterized by?
Low resistance and low melting point by "justquikr.com"
Why can not copper wire be used as a fuse wire?
The fuse needs a low melting point and reletivelyhigh resistance so that it melts at the proper current
What type of wire is used in fuse and why?
Fuse wire is usually made with metal that has a low melting point, e.g. tin, to lessen the risk of fire.
What material is used to make a fuse wire?
The material suitable for making a fuse wire should have a low melting pt. so that it can easily melt and cut off the flow of current and save the electrical appliance...
Does the material used for a fuse wire need to have a low or a high melting point - a low or high ductility - a low or high resistivity?
The material for the fuse wire should have low resistance and a low melting point. Ductility is a incidental factor. As the current flow nears the fuse rating, the high current flow causes the wire to heat up quickly. It then melts, opening (breaking) the circuit. This is how the fuse limits the amount of current that can flow through a circuit.
Which material is using for fuse wire?
zinc, copper, silver, aluminum, alloys or metals that have low melting point
Which alloy is used to make electric fuse?
Solder ( an alloy of Lead and Tin) is used to make fuse wire because of its very low melting point.
Why is copper used in fuses?
Copper is used in the contact points in fuse boxes because it will oxidize and you can separate the points of contact. If it was made if iron and rusted, it will 'weld' the link together and then it is no longer a fuse.
