Why do capacitors have to be grouped?

Necessity of capacitor combination : In certain instances, we may not be able to get a required value of capacitance and a required voltage rating.

Why do parallel grouped capacitors store more charge?

Since the voltage across parallel-grouped capacitors is the same, the larger capacitor stores more charge. If the capacitors are equal in value, they store an equal amount of charge. The charge stored by the capacitors together equals the total charge that was delivered from the source. QT= Q1+ Q2 + Q3+..+ Qn
