What diameter of cylindrical wire should be used

Reference no: EM13651134

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 410 A/cm². What diameter of cylindrical wire should be used to make a fuse that will limit the current to 0.55 A?
