In the figure, a uniform electric field vec$(E)$ collapses. The vertical axis scale is set by $E_5=1\mathrm{.}5{10}^5\frac{N}{C},$ and the horizontal axis scale is set by $t_5=24\mathrm{.}0s.$ Calculate the magnitude of the displacement current through a $3\mathrm{.}0m^2$ area perpendicular to the field during each of the time intervals $a,b,$ and $c$ shown on the graph. $($Ignore the behavior at the ends of the intervals.$)$
