NEET Physics (general) MCQ Question
Which of the following statements about the electrostatic potential and capacitance are correct?
The insertion of a dielectric material increases the capacitance of a capacitor.
The voltage across a capacitor remains constant when a dielectric is inserted while connected to a supply.
The energy stored in a capacitor decreases when a dielectric is inserted after disconnecting from a supply.
The energy stored in a capacitor is directly proportional to the square of the voltage across its plates.
Correct Answer
Detailed Explanation
The insertion of a dielectric material increases the capacitance of a capacitor, as stated in the context. The voltage across the capacitor changes when a dielectric is inserted after disconnecting from the supply, affecting energy stored.
