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.
Oh, dude, so like, capacitance is just the ratio of charge to voltage, right? So if you've got 60 coulombs of charge and 12 volts of potential difference, you just divide 60 by 12 and boom, you get 5 farads. Easy peasy lemon squeezy.
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.
