Importance of the displacement current

Using the example of a parallel plate capacitor being charged by a current, we show how Ampère's law in its original form gives inconsistent results for the magnetic field around the wires, then show how the idea of displacement current can be introduced to fix this problem.

So... current into condeser is proportional to the rate of increase of EMF and to the permittivity of a dialectric? Also when capacitor gets charged the current will drop and this will induce more EMF slightly aiding the current, if you make L large enough, can you get the circuit to oscillate? Also, is I/2pi*r = H?
