A. Effective capacitance of a series combination of capacitors is always smaller than the smallest capacitance of the capacitor in the combination.
B. When a dielectric medium is placed between the charged plates of a capacitor, displacement of charges cannot occur due to insulation property of dielectric.
C. Increasing of area of capacitor plate or decreasing of 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.

Choose the correct answer from the options given below.
- (A)A, B and C only
- (B)C and D only
- (C)A, C and D only✓ Correct
- (D)B and D only
Answer: (C)
Solution
Statement A is correct: for series capacitors , which makes smaller than the smallest capacitance in the chain. Statement B is wrong: a dielectric between charged plates becomes polarized, so bound charges are displaced to its surfaces even though free charge does not flow through it. Statement C is correct: since , increasing the plate area or reducing the dielectric thickness both raise the capacitance. Statement D is correct: for a point charge depends only on , so concentric spheres centred on the charge are equipotential surfaces. The correct statements are A, C and D.
