In the figure, a uniform electric field E→ collapses. The vertical axis scale is set by ES = 1.5×105 N/C, and the horizontal axis scale is set by tS = 24.0 μs. Calculate the magnitude of the displacement current through a 3.0 m2 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.)
