In a series circuit, p.d is shared between all the components in the circuit . Therefore, if the capacitors store the same charge on their plates but have different p.ds, the p.d across C 1 is V 1 and across C 2 is V 2; The total potential difference V is the sum of V 1 and V 2; V = V 1 + V 2. Rearranging the capacitance equation for the p.d V means V 1 and V 2 can be written as:
