Why multiple capacitors in parallel?
A couple reasons come to mind. Lower ESR. The effective ESR of the capacitors follows the parallel resistor rule. For example, if one capacitor''s ESR is 1 Ohm, putting ten in parallel makes the effective ESR of the capacitor bank ten times smaller.

The alignment is improved by either increasing the field or by decreasing the temperature. The alignment is due to the electric dipole moment p which is proportional to the electric field. To illustrate the dipole effects taking place within a slab of dielectric, we can take a charged parallel plate capacitor (battery disconnected) which has a fixed charge q and provides a uniform …
