A fuse wire melts when its temperature rises to its melting point. If a fuse wire of length , cross sectional radius , density is heated due to passage of a current through it then its equilibrium temperature is one when rate of heat produced in it due to Joule heating is equal to the rate at which heat is radiated to its surrounding which is given as
Thus the equilibrium temperature of a fuse wire does not depend on its length.
Thus the equilibrium temperature of a fuse wire does not depend on its length.
