1.	the current rating of a fuse wire is i if its length is doubled and radius s made one fourth of its value what will be its new current rating?
Answer» Since RESISTANCE is directly proportional to length and indirectly proportional area of CROSS section. Therefore the resistance increases to 8 times Since current is indirectly proportional to resistance therefore the NEW current rating WOULD be one eighth of I
