Why are capacitors connected in parallel?
Connecting capacitors in parallel results in more energy being stored by the circuit compared to a system where the capacitors are connected in a series. This is because the total capacitance of the system is the sum of the individual capacitance of all the capacitors connected in parallel.

Why does a series capacitor have more capacitance?
In series, the capacitance is less. When the capacitors are connected between two common points they are called to be connected in parallel. When the plates are connected in parallel the size of the plates gets doubled, because of that the capacitance is doubled. So in a parallel combination of capacitors, we get more capacitance.
