The faraway/distance between the plates

The more faraway/distant the plates are, the short the free electrons on the far plate feel the push of the electrons that are being added to the negative plate. This makes it harder to feature more negative charges to the negative plate. If the plates are closer to every other, the present would flow through a brief circuit. This suggests that the capacitance of a parallel plate is inversely associated with the plate separation.

Area of the plates

It’s tons easier to feature charges to a capacitor if the parallel plates have an enormous area. Two wide metal plates would give two repelling like charges a greater range to opened up across the plate, making it easier to feature tons more charge to at least one plate. Likewise, a really small plate area would cause the electrons to urge cramped together earlier, making it harder to urge an outsized difference responsible for a given voltage.
