A fuse in an electric circuit is a wire that is designed to melt, and thereby open the circuit, if the current exceeds a predeter- mined value. Suppose that the material to be used in a fuse melts when the current density rises to 440 A/cm2 . What diameter of cylindrical wire should be used to make a fuse that will limit the current to 0.50 A?
