The displacement current density, $$\mu_0 \epsilon_0 \frac{\partial \textbf{E}}{\partial t}$$

has units of (N/A^2) (C^2/Nm^2) N/Cs = Ns^2/(Cm^2)

which is not the same for current density: C/sm^2

Where is the discrepancy?

  • $\begingroup$ You can't delete it because it has an upvoted answer. But in this case, it's your answer, so you can delete the answer and then you should be able to delete the question. That being said, I think this is a good question and answer - even though it was caused by a minor mistake, someone else could easily make the same mistake, and leaving this post here would help them. (Plus, free rep :-P) $\endgroup$ – David Z Apr 22 '15 at 6:03
  • $\begingroup$ Well then. I guess I'll just leave this here. $\endgroup$ – user279043 Apr 22 '15 at 6:12

It's cause $\mu_0$ is not part of the displacement current density.
