You need to design a 1.3 A fuse that "blows" if the current exceeds 1.3 A . The fuse material in your stockroom melts at a current density of 550 A/c m 2 . What diameter wire of this material will do the job?
We are tasted with building a cylindrical shaped fuse that “blows” if the current exceeds 2.0A. The fuse material you have melts at a current density of 876 A/cm2. You have a large assortment of this material that has different diameters. What diameter of wire will do the job?
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)
