How does the (i) thickness and (ii) length of a fuse wire depend on it's current rating?
Answer
(i) Thickness of the fuse wire — 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.
(ii) Length of the fuse wire — The current rating of the fuse wire is independent of it's length.
