Identify the correct statements : 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 dielect

Step-by-step solution

A. Effective capacitance of series combination is always smaller than the smallest capacitance - TRUE. For series: 1 C_ eff = 1 C₁ + 1 C₂ + , therefore C_ eff B. Dielectric prevents charge displacement - FALSE. A dielectric allows polarization (displacement of bound charges) but prevents free charge movement. It does not prevent displacement of bound charges. C. Increasing area or decreasing thickness increases capacitance - TRUE. From C = ₀ _r A d , increasing A or decreasing d increases C . D. Concentric spherica
