ratio of capacitance of capacitor is given by charge\potential
Not sure what you are asking.There are two formulae for working out equivalent capacitance:Two capacitors in parallelThe equivalent single capacitance is the sum of the two capacitors: Ce = C1 + C2Two capacitors in seriesThe equivalent single capacitance is the reciprocal of the sum of the reciprocals of the two capacitors: 1/Ce = 1/C1 + 1/C2⇒ Ce = C1C2/(C1+C2)So you can replace two capacitors by a single one, or a single one by two.
The reciprocal of capacitance is elastance. This is perhaps more convenient for circuit analysis than capacitance. In a circuit, a capacitor can be neglected if the elastance is set to zero. In the same way, a resistor/inductor can be ignored if its resistance/inductance is set to zero.
The capacitance of two spheres can be calculated using the 'method of images' repeatedly. This gives the result as a fast converging series. Details: http://www.iue.tuwien.ac.at/phd/wasshuber/node77.html
If the ratio of similarity is 310, then the ratio of their area is 96100.
an eqivalent ratio is an ratio that is equal or you can simplfiy it
Two similar (non-polarized) capacitors connected in parallel will have double the capacitance of one, while two similar capacitors connected in series will have half the capacitance of one, so the ratio is four.
You seem to be mixing up your terminology. There is no such thing as 'self-capacitance of an inductor'! If you know the frequency and equivalent capacitance for two capacitors, then you can find the equivalent capacitive reactance of the capacitors, but that's not what you seem to be asking! I suggest you rephrase the question.
Equivalence capacitance for system of two capacitors in parallel circuit is Ce = C1 + C2 Equivalence capacitance for system of two capacitors in serial circuit is 1/Ce = 1/C1 + 1/C2
capacitance C=C1+C2+C3
With capacitors in parallel you can just add the microfarads.
The total capacitance from capacitors that are connected in series are added up inversely; 1/Ctotal = 1/C1 + 1/C2 + ... + 1/Cn, where Cn is the capacitance of the nth capacitor.

Capacitors are one of the standard components in electronic circuits. Moreover, complicated combinations of capacitors often occur in practical circuits. It is, therefore, useful to have a set of rules for finding the equivalent capacitance of some general arrangement of capacitors. It turns out that we can always find the equivalent capacitance by repeated application oftwosimple rules. These rules related to capacitors connected in series and in parallel.
The total capacitance is one fourth of the capacitance of the individual capacitors. The voltage rating is four times the voltage rating of the individual capacitors (however to prevent uneven charging of the four capacitors and failure of one or more they must be paralleled with a voltage divider composed of four equal value resistors).
