Dielectric Polarization
When a current interacts with a dielectric (insulating) material, the dielectric material will respond with a shift in charge distribution with the positive charges aligning with the electric field and the negative charges aligning against it. By taking advantage of this response, important circuit elements such as capacitors can be made.
Does continuously moving dielectric changes capacitance?
The dielectric moves very fast and the time a single atom spends in the capacitor''s field is negligible compared to $tau$. Since the dielectric is uncharged and has no time to become polarized before leaving the capacitor again, the latter will behave as if in a vacuum. This stays true if the dielectric accelerates without transition to case 3.
