WebFeb 6, 2016 · $\begingroup$ I wrote the answer with static charges in mind but metals can have E-fields within them; that is the reason for electric currents flowing. The reduction in E-field in a medium is the reason for the capacitance of a capacitor increasing when a dielectric is introduced and this effect is relevant in ac circuits. $\endgroup$ – WebIn a dielectric, the charges are valence electrons that are stuck inside atoms of a crystal or polymer, and so current doesn’t flow at all. The electric field, however, still exerts a force on the charges. While the individual electrons remain tied to their parent atoms, they …
