Parallel-Plate Capacitor. While capacitance is defined between any two arbitrary conductors, we generally see specifically-constructed devices called capacitors, the utility of which will become clear soon.We know that the amount of capacitance possessed by a capacitor is determined by the geometry of the construction, so let''s see …

electrostatics

You cant make the area of plates zero. If you make it very small, then it would still act as a capacitor but would have negligible capacitance. It would act similar to a broken circuit. If the area of the plates keeps on decreasing continuously, then the capacitance will also keep on decreasing proportionately.
