Identify the correct statements:
[A.] Effective capacitance of a series combination of capacitors is always smaller than the smallest capacitance of the combination. [B.] When a dielectric medium is placed between charged plates of a capacitor, displacement of charges cannot occur due to insulation property of dielectric. [C.] Increasing area of a capacitor plate or decreasing thickness of dielectric is an alternate method to increase the capacitance. [D.] For a point charge, concentric spherical shells centered at the location of the charge are equipotential surfaces.
