Remember, that for any parallel plate capacitor V is not affected by distance, because: V = W/q (work done per unit charge in bringing it from on plate to the other) and W = F x d. and F = q x E. so, V = F x d /q = q x E x d/q.
Parallel Plate Capacitor: Derivation, Electric Field, Usage
A parallel plate capacitor has two conducting plates with the same surface area, which act as electrodes.

How a capacitor is made up of two conductive electrodes?
A capacitor is usually made up of two conductive electrodes in which an insulating material called dielectric separates them as shown in (Fig. 9.6).
