Capacitors in Parallel Figure 2a shows a parallel connection of three capacitors with a voltage applied. Here the total capacitance is easier to find than in the series case. To find the equivalent total capacitance C p, we first note that the voltage across each capacitor is V, the same as that of the source, since they are connected directly to it through a conductor.

Capacitors in parallel with voltage sources

The problem is that you can not connect an ideal voltage source of a given voltage in parallel with an ideal capacitor that has some initial voltage different from the source voltage. Once these two are connected, our definitions of "ideal voltage source" and "in parallel" demand that the voltage across the capacitor instantaneously changes.
