Unformatted text preview: I max = 35 A . (b) the value of V ; Solution: = 2 f = 4 . 78 10 2 rad/s 1 I = dQ dt = C dV dt =CV sin t, I max = CV ,C = A d . V = I max C = I max d A = 6 . 75 10 3 V (c) the maximum value of d E /dt between plates. Solution: I D = d E dt ( d E dt ) max = I max = 3 . 95 10 6 V m/s. Bonus Problem A 1500nF capacitor with circular parallel plates 2 cm in diameter is accumulating charge at the rate 38 mC/s at some instant in time. (a) What will be the induced magnetic eld strength 10 cm radially outward from the center of the plates? Solution: B (2 r ) = I. B = I 2 r = 7 . 6 108 T (b) What will be the value of the eld strength after the capacitor is fully charged? Solution: Since I = 0 , B = 0 . 2...
