How does current flow in a circuit with a capacitor?
Assuming the capacitor is not initially charged, then before it is connected to the battery each metal plate has an equal amount of protons (positive charge) and highly mobile electrons (negative charge) so that each plate is electrically neutral and there is no voltage (potential difference) between the plates. When the capacitor is connected ...

When we find the electric field between the plates of a parallel plate capacitor we assume that the electric field from both plates is $${bf E}=frac{sigma}{2epsilon_0}hat{n.}$$ The factor of two in the denominator comes from the fact that there is a surface charge density on both sides of the (very thin) plates.

Each terminal of the capacitor is then dipped in the ink and the parts are fired in kilns.
