Physics Electrostatics Potential & Capacitance JEE Main 2026 - ( Capacitance ) MCQ (Single Correct)

Effective capacitance of a series combination of capacitors is always smaller than the smallest capacitance of the capacitor in the combination.
B and D Only

When a dielectric medium is placed between the charged plates of a capacitor, displacement of charges cannot occur due to insulation property of dielectric.
A, B and C Only

Increasing of area of capacitor plate or decreasing of thickness of dielectric is an alternate method to increase the capacitance.
C and D Only

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, C and D Only

The correct answer is:

Effective capacitance of series combination is always smaller than the smallest capacitance - TRUE. For series: , therefore
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.
Increasing area or decreasing thickness increases capacitance - TRUE. From , increasing or decreasing increases .
Concentric spherical shells centered at a point charge location are equipotential surfaces - TRUE. For a point charge, the potential at distance is , which depends only on distance, making concentric spheres equipotential surfaces.
Correct statements: A, C, D
