About Maxwell's displacement current, judge the following items. I. It is obtained from the variation of the magnetic flux, for example, between the plates of a capacitor. II. The displacement current establishes a symmetry between the electric and magnetic fields by indicating that, just as the temporal variations of the magnetic field produce an electric field (Faraday's Law), it is possible that magnetic fields are created from temporal variations of the electric field . III. The displacement current was fundamental to the understanding that light is an electromagnetic wave. IV. Ampere's Law works independently of the existence of the Maxwell displacement current, as long as we consider only stationary electrical currents.

About Maxwell's displacement current, judge the following items.

I. It is obtained from the variation of the magnetic flux, for example, between the plates of a capacitor.

II. The displacement current establishes a symmetry between the electric and magnetic fields by indicating that, just as the temporal variations of the magnetic field produce an electric field (Faraday's Law), it is possible that magnetic fields are created from temporal variations of the electric field .

III. The displacement current was fundamental to the understanding that light is an electromagnetic wave.

IV. Ampere's Law works independently of the existence of the Maxwell displacement current, as long as we consider only stationary electrical currents.
