Parallel Plate Capacitor
Yes, the capacitance of a parallel plate capacitor can be adjusted by changing the distance between the plates, the area of the plates, or the type of dielectric material used. For instance, bringing the plates closer together, increasing the plate area, or using a dielectric material with a higher dielectric constant will increase the capacitance.

Electric field in a parallel plate capacitor
A capacitor is a device used in electric and electronic circuits to store electrical energy as an electric potential difference (or an electric field) consists of two electrical conductors (called plates), typically plates, cylinder or sheets, separated by an insulating layer (a void or a dielectric material). ...
Field between the plates of a parallel plate capacitor using …
Consider first a single infinite conducting plate. In order to apply Gauss''s law with one end of a cylinder inside of the conductor, you must assume that the conductor has some finite thickness. In doing this, the surface charge density $sigma$ must be spread over ...
Electric field in a cylindrical capacitor
In this page we are going to calculate the electric field in a cylindrical capacitor. A cylindrical capacitor consists of two cylindrical concentric plates of radius R 1 and R 2 respectively as seen in the next figure. The charge of the internal plate is +q and the charge of the external plate is –q. ...
Why does the area of the plates affect the capacitance?
You basically know the result you want and determine the size of the capacitor you need. A larger capacitor, with a larger capacity, will hold a bigger charge at the same voltage. Doubling the area will double the capacitance (in case of a plate capacitor), so for 4
Why does the area of the plates affect the capacitance?
If you have a larger plate, the charge can distribute over a larger area, there is less "pileup" and therefore a smaller "pushback force". This is why, with larger plates, you get a …

5.1: Introduction
In the highly idealized capacitors of this chapter, the linear dimensions of the plates (length and breadth, or diameter) are supposed to be very much larger than the separation between them. This in fact is nearly always the case in real capacitors, too, though perhaps not necessarily for the same reason.
Are capacity and capacitance the same?
So if the capacitor with larger plate separation holds the same charge as that with the smaller separation then the voltage on the capacitor with the larger separation has to be greater. Yes your answer helps but please also include the answer/explanation for the question I wrote in title
Capacitor
In electrical engineering, a capacitor is a device that stores electrical energy by accumulating electric charges on two closely spaced surfaces that are insulated from each other. The capacitor was originally known as the condenser, [1] a term still encountered in a few compound names, such as the condenser microphone..
