Capacitors in Series (1 Viewer)

Hi,

When capacitors are connected in series then why charge remains same on each capacitor and why voltage differs on each capacitor?

Regards,

Charge doesn't come out of nowhere--and it doesn't flow across the gap. So the + charge on one side of capacitor 1 must be balanced by an equal - charge on the adjacent side of the capacitor 2. (The net charge on the capacitor is zero; and the net charge on the two plates connected by the wire is also zero.)

As far as voltage goes, how does voltage depend on Q and C?
 
But why Q differs in parallel combinations of capacitors?

In that case the voltage is the same, but the total Q is shared among all the parallel capacitors. Each gets a portion according to V and C.
