I'm trying to marry the concepts from my EM course with what I've been doing in my lab course. Correct me if I'm wrong, in a plain RC circuit, when closed with a DC source, the capacitor initially acts as a short (voltage is zero across the terminals, while I is max), until after a few microseconds the voltage increases exponentially to the one I'm administering (consequently I drops down to 0 ideally).
What's happening to the dielectric in the capacitor in these first few moments? The current through the cap is initially nonzero, meaning charge is flowing through it and the dielectric is quickly becoming polarized, but why is the voltage zero at the terminals initially? There's a circulation of E between the capacitor plates, so why isn't there any difference in potential on the terminals?
