When one of the plates of one capacitor is brought closer to the other plate:a)The voltage on the capacitor whose plates comecloser is greater than the voltage on the capacitorwhose plates are not movedb)The voltage on the capacitor whose plates comecloser is smaller than the . For example, imagine a combination of capacitors with two capacitors in series, with C1 = 3 103 F and C2 = 1 103 F, and another capacitor in parallel with C3 = 8 103 F. First, tackle the two capacitors in series: This is the single equivalent capacitor for the series portion, so you can treat this as a single capacitor to find the total capacitance of the circuit, using the formula for parallel capacitors and the value for C3: For another combination of capacitors, three with a parallel connection (with values of C1 = 3 F, C2 = 8 F and C3 = 12 F) and one with a series connection (with C4 = 20 F): The approach is basically the same as in the last example, except you handle the parallel capacitors first. Total charge of the parallel combination, will be divided in each capacitor according to it's capacitance value but voltage across each capacitor will be same and at steady state condition it is exactly equal to the applied voltage. The reason being the top plate of capacitor, C1 is coupled to the upper plate of C2 that is attached to the upper plate of C3 and so forth.
