Answer 2

• The relation between nichrome and fuse wire is that they are made of alloys.

• Nichrome is an alloy of nickel, chromium, and iron.

       Similarly, fuse wire is an alloy of lead and tin

       So, Nichrome: Ni, Cr, Fe

             Fuse wire: Pb, Sn

• Fuse wire is used to break the circuit when a large amount of current flows through it in order to save the appliance from any damage.

• Tin and lead have high resistance and they have a low melting point, therefore, these are used as alloys for fuse wire.
