Question

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

Answer 1

Answer:

A copper wire cannot be used as fuse wire because it has a high melting point. It will not melt easily when a high electric passes through it and may damage the electric appliances

Answer 2

Metal wire or metal strip cannot be used insted of fuse wire as it has low melting point. This property is useful as when excess of current is passed through the wire the fuse gets heated up and melts, thus breaking the circuit and hence short circuit or overloading does not take place.

Hope this helps...
