There are three main factors (Dielectric Constant of the material, Area of the plates, and Distance between the plates) affecting the capacitance of the capacitors that will be discussed here.
There are three basic factors of capacitor construction determining the amount of capacitance created. These factors all dictate capacitance by affecting how much electric field flux (relative difference of electrons between plates) will develop for a given amount of electric field force (voltage between the two plates):
One relatively easy factor to vary in capacitor construction is that of plate area, or more properly, the amount of plate overlap. The following photograph shows an example of a variable capacitor using a set of interleaved metal plates and an air gap as the dielectric material:
These factors all dictate capacitance by affecting how much electric field flux (relative difference of electrons between plates) will develop for a given amount of electric field force (voltage between the two plates): PLATE AREA: All other factors being equal, greater plate area gives greater capacitance; less plate area gives less capacitance.
For a fixed value of charge, increasing the capacitance of the capacitor should decrease the potential difference across the plates, and vice-versa. To investigate this prediction, give the capacitor (which still has its plates about 2 mm apart) one or two “units” of charge and note the potential difference.
The value of the capacitor is determined by 3 physical factors: the amount of surface area of the parallel metallic plates (A); the separation or distance between the plates (d) and the insulating material or dielectric between the plates. The capacitance is given by the expression on Figure 4: (d) between plates in a capacitor.
