lets say ive got three capacitors in series ( 4 , 8 and 12 micro farad) the total capacitance will be smaller than the smallest capacitor and the smallest capacitor will drop the biggest voltage to keep Q constant. i cant understand why you would waste two capacitors to a value smaller than the smallest capacitor, would it not be easier to just stick with one capacitor at a constant value. or is there a purpose beyond my scope to this???
