A constant current, I, is applied to charge a parallel plate capacitor of area A and separation between plates, d.
What is the E field strength inside the capacitor as a function of time?
What is the displacement 'current' density between the plates, and what is its orientation relative to the E field?
Is the displacement current real - i.e. are charges transported between plates?
Compare the magnitude of the total displacement current to the magnitude of the current brought through wires to charge the plates. Sketch the B field between the plates. Is your sketch similar to the one in problem 4?
