In Fig. 32-40, a parallelplate capacitor is being discharged by a current i = 5.0 A. The plates are square with edge length L = 8.0 mm. (a) What is the rate at which the electric field between the plates is changing? (b) What is the value of  around the dashed path, where H = 2.0 mm and W = 3.0 mm?
