A fuse in an electric circuit is a wire

Reference no: EM13562870

A fuse in an electric circuit is a wire that is designed to melt,and thereby open the circuit, if the current exceeds apredetermined value. Suppose that the material to be used in a fusemelts when the current density rises to 470 A/cm2. What diameter of cylindrical wire should be used to make a fuse that will limit the current to 0.49 A?
