1. The problem statement, all variables and given/known data A parallel-plate capacitor with circular plates of radius 1.7 m is being charged. Consider a circular loop centered on the central axis between the plates. The loop has a radius of 2.6 m and the displacement current through the loop is 2 A. (a) At what rate is the electric field between the plates changing? 2. Relevant equations maxwell's equations 1) electric flux through a closed surface = charge enclosed by the surface divided be e0 2) magnetic flux through an open surface = u0 times current through the surface 3) EMF in a closed path = derivative of magnetic flux through the path WRT time 4) currents cause magnetic fields 3. The attempt at a solution there's an E-field in the capacitor C = e0*A/d q = C*V E = q/(A*e0) SO dE/dt = dq/dt * 1/(A*e0) I feel like I'm missing something. Does a changing E-field induce a current in a closed path? is that current proportional to the electric flux through the path?
