Capacitors Physics A-Level
because the applied potential difference is shared by the capacitors, the total charge stored is less than the charge that would be stored by any one of the capacitors connected individually to the voltage supply.

Time taken to charge the capacitor
The voltage across the capacitor (Vc) is initially zero but it increases as the capacitor charges. The capacitor is fully charged when Vc = Vs. The charging current (I) is determined by the voltage across the resistor (Vs - Vc): Charging current, I = (Vs - Vc) / R (note that Vc is increasing) At first Vc = 0V so the initial current,

What are the behaviors of capacitors and inductors at time t=0?
A fully discharged capacitor, having a terminal voltage of zero, will initially act as a short-circuit when attached to a source of voltage, drawing maximum current as it begins to build a charge.

Why is charge the same on every capacitor in series?
For various practical reasons, you would probably want resistors in parallel to help balance the DC charge on the capacitors. But the theory of your question can be explained by imagining each of the capacitors as a rubber membrane. If you pull on one side, that creates or displaces volume on the other side that needs to go somewhere. ...
