Answer :

A fuse wire is basically a safety measure to prevent electric fires and short circuits. Fuse wire is a conductor wire with a very low melting point. Low melting point is the main characteristic here.

Some devices require very high amount of current, the flow of so much current can sometime cause the melting of the insulating wire due to heating effect of the electric current.


This can result into severe electric fires. To prevent these situation a fuse is introduced into the circuit, which is made up of a low melting point conductor wire.

The wire inside the conductor melts and breaks the circuit as soon as the heating due to current increases.


This prevents further fire or electric short circuit.
