Solution

An electric fuse is a safety device which is used to limit the current in an electric circuit.
An alloy of lead and tin is used as the material of the fuse wire because its melting point is low and it has high specific resistance.
This allows the fuse wire to melt when the current exceeds a specified rating, cutting off the electricity supply to our devices, therefore keeping them safe from damage.
