A fuse in an electric circuit is a wire that is designed to melt, and thereby open the circuit, if the current exceeds a predetermined value. Suppose that the material to be used in a fuse melts when the current density rises to 329 A/cm2. What diameter of cylindrical wire should be used to make a fuse that will limit the current to 0.3 A?
(Express your answer in units of mm i.e. 10-3 m, up to two decimal places)
