Answer
(i) The current rating of the fuse wire is directly proportional to the thickness of the fuse wire. Higher the thickness of fuse wire, higher will be the current rating.
Hence, 20 A wire will be thicker than the 5 A wire.
(ii) The current rating of the fuse wire is independent of it's length. Hence, both fuse wires may be of same length.
