 Well I think this confusion over terminology is probably more than half the problem we have with Catt et al. People are using different definitions of displacement current and Im not sure your definition, (dD/dt) has percolated all the way down thro the electrical engineering community. You can have disp current in a dielectric of course, but were talking about free space here, yes? In dielectrics,you can get a real measureable disp current. Un vacuo, you cant. What 3was Maxwell talking about? dielectrics or vacuum? 02:34
