Kirchhoff's first law on a discharging capacitor?
Consider a charged capacitor that is now switched to being in a series circuit with a resistor. As I understand it (and probably incorrectly) the charge on the negative plate moves away from the plate and is discharged across the resistor. But applying Kirchhoff's first law on the plate must mean that since a current is leaving, a current must be coming in?!? Does this mean there is a current across the gap. I've read that charge cannot travel across the gap. Could someone please help me understand what is actually happening? Thanks very much.
