1) Two sections of a long thick cable are fed with a unifo current given by J=0.5cos(100t)2A/m2. The rad of the cable is equal to a=5cm and the separat between the two sections w=2mma. Assume t the current flows in such a way that the surface char on the two sides of the gap are uniformly distributed: the fringing of the field lines outside the gap is negligi a) Determine the electric field in the gap between ends of the two sections, as a function of t. b) Find the displacement current through a circl radius
