Fuse wire is charaterized by high resistance and low melting point to avoid surge of ac current through it.
resistance means the te power to resist the heat or the electric current/ eg: tungsten which is used to make the filament of the bulb has a high melting point even when it burns on a high temperature so it has a high resistance, whereas in the wire of an electrical fuse has a low melting point as it burns at a high temperature...
Metals used in fuses must have a low melting point so they can easily melt when there is an overload. They also need to have high electrical conductivity to ensure efficient flow of current.
A metal used in a fuse must have a low melting point to ensure it can melt and interrupt the circuit when necessary. It should also have high conductivity to allow current to flow easily through it. Additionally, the metal should have good mechanical properties to withstand the electrical and thermal stresses during operation.
No, the word atom does not mean fuse. Atom refers to the smallest unit of a chemical element that retains the properties of that element. Fuse, on the other hand, refers to joining or melting materials together by heating.
Platinum has a higher melting point than copper, so it requires more heat to fuse. Additionally, platinum has lower thermal conductivity compared to copper, causing it to retain heat and weaken more easily in high-temperature environments like a glass-making process.
Low resistance and low melting point by "justquikr.com"
low resistivity and low melting point.
It has high specific resistance and low melting point.........
The fuse needs a low melting point and reletivelyhigh resistance so that it melts at the proper current
Yes they do

This is necessary because a fuse is a protection against an overcurrent; excessive current produce melting.
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...
Copper is a metal having high melting point and very low specific resistance. in case of excess current flowing in the circuit it will not be able to melt wire quickly and break the circuit protecting it.
No, a fuse of a higher amperage rating will not usually have a higher melting point link. The higher amperage fuse will use a wider link or a link of larger diameter.
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.
Spelter, sometimes known as zinc, is used to fuse metals with a higher melting point. The actual melting point of spelter is 787.15 degrees Fahrenheit.
