Solution:
A fuse wire repeatedly gets burnt when used with a good heater. It is advised to use a fuse wire of greater radius."The resistance of a wire is directly proportional to the length of the wire. Also, the resistance of the wire is inversely proportional to the radius of the wire. " Since the length of a fuse wire is fixed, and therefore, in order to decrease the resistance of a wire, it is advised to use a wire of more radius.
