The current density equation states that J = I/A$J = I/A$.

But I got a question that asking the current density over an infinite plate. Say the current $I_0$ flows into the infinite plate that extent infinitely on z$z$ direction from x = 0$x = 0$ to d$d$, What`sWhat's the current density on the plate? The plate in unspecified on y$y$.

I have asked a professor regarding this, and the answer is J = I$J = I$. I have trouble to understand why infinite count as 1 in this case. Could anyone sent some help?

Thanks in advance.
