For parallel capacitors, the analogous result is derived from Q = VC, the fact that the voltage drop across all capacitors connected in parallel (or any components in a parallel circuit) is the same, and the fact that the charge on the single equivalent capacitor will be the total charge of all of the individual capacitors in the parallel combination.

In parallel, the capacitor with the lowest voltage rating specifies the parallel combination voltage rating. In series, capacitor voltage rating is inversely related to capacitance, that is, the necessary voltage rating of each capacitor must satisfy C 1 V 1 = C 2 V 2 = C n V n. The lowest CV will be the limiting capacitor. 29.1.2

Internally fused unit construction Internally fused capacitors protect each element with its own fuse. With this design, individual elements that fail are isolated, and there

The voltage ( Vc ) connected across all the capacitors that are connected in parallel is THE SAME. Then, Capacitors in Parallel have a “common voltage” supply across them giving: VC1 = VC2 = VC3 = VAB = 12V In the following circuit the capacitors, C1, C2 and C3 are all connected together in a parallel branch between points A and B as shown.
When 4, 5, 6 or even more capacitors are connected together the total capacitance of the circuit CT would still be the sum of all the individual capacitors added together and as we know now, the total capacitance of a parallel circuit is always greater than the highest value capacitor.
