An equation can be derived for the capacitance of one capacitor that would have the equivalent capacitance of these two capacitors. The total charge stored on the two capacitors is Q = Q 1 + Q 2 . The voltage across each capacitor is the same and is equal to the voltage of the battery (V) ; therefore, Q 1 = C 1 V and Q 2 = C 2 V, or for the equivalent capacitor, Q = C eq V .
