The voltage across the 100uf capacitor is zero at this point and a charging current ( i ) begins to flow charging up the capacitor exponentially until the voltage across the plates is very nearly equal to the 12v supply voltage. After 5 time constants the current becomes a trickle charge and the capacitor is said to be “fully-charged”.
The capacitors ability to store this electrical charge ( Q ) between its plates is proportional to the applied voltage, V for a capacitor of known capacitance in Farads. Note that capacitance C is ALWAYS positive and never negative. The greater the applied voltage the greater will be the charge stored on the plates of the capacitor.
The greater the applied voltage the greater will be the charge stored on the plates of the capacitor. Likewise, the smaller the applied voltage the smaller the charge. Therefore, the actual charge Q on the plates of the capacitor and can be calculated as: Where: Q (Charge, in Coulombs) = C (Capacitance, in Farads) x V (Voltage, in Volts)
When a capacitor charges, it stores electrical energy by accumulating charge on its plates; however, the total charge in the entire circuit remains unchanged. As current flows into one plate of the capacitor, an equal amount of charge must leave the other plate to maintain balance.
The capacitance of a capacitor is a parameter that tells us how much charge can be stored in the capacitor per unit potential difference between its plates. Capacitance of a system of conductors depends only on the geometry of their arrangement and physical properties of the insulating material that fills the space between the conductors.
When battery terminals are connected to an initially uncharged capacitor, the battery potential moves a small amount of charge of magnitude Q from the positive plate to the negative plate. The capacitor remains neutral overall, but with charges + Q and − Q residing on opposite plates.

Why capacitors in series at different potential store same charge?
Since the total charge on the two plates b b and c c is zero an charge of +q + q must be induced on plate c c which in turn induces a charge of −q − q on plate d d. Thus each capacitor stores the same amount of charge all because the total charge on plates b b and c c must always be zero.
