B
The stored energy in a capacitor remains the same regardless of the dielectric material used.
C
Capacitance is independent of the distance between the plates of a capacitor.
D
The potential difference across a capacitor decreases when a dielectric is inserted after disconnection from the voltage supply.
Correct Answer
Option A
Detailed Explanation
Inserting a dielectric material, such as a mica sheet, increases the capacitance of the capacitor, as indicated in the NCERT context regarding the effect of dielectric on capacitance.
