Why can't metal wire or metal strip be used as a fuse wire?

Why any metal wire or metal strip cannot be used in place of fuse wire?

A metal wire or metal strip cannot be used in place of a fuse wire because they do not have a low melting point like a fuse wire.

Explanation:

A fuse wire is a safety device used to protect electrical circuits from excessive current. It is designed to melt and break the circuit when the current exceeds a certain limit. Fuse wires are made from materials with low melting points, such as tin, lead, or alloys. This low melting point allows the fuse wire to melt quickly and interrupt the flow of current.

On the other hand, metal wires or metal strips used in electrical circuits are made from materials with high melting points, such as copper or aluminum. These materials are chosen for their conductivity and durability, but they do not have the ability to melt and break the circuit like a fuse wire.

Using a metal wire or metal strip in place of a fuse wire would not provide the necessary protection against excessive current. If the current exceeds the safe limit, the metal wire or strip would not melt and break the circuit, potentially leading to damage or even fire.
