NEET Physics (general) MCQ Question

Type: MCQ-conceptual-Easy-Class 12

Which of the following statements about the electrostatic potential and capacitance is correct?

A

Inserting a dielectric increases the capacitance of a capacitor when connected to a voltage supply.

B

The electrostatic potential energy stored in a capacitor is independent of the applied voltage.

C

The work done to separate two charges is negative when they are of the same sign.

D

A capacitor stores energy by increasing its charge while its voltage remains constant.

Correct Answer

Option A

Detailed Explanation

According to the NCERT context, inserting a dielectric increases the capacitance of a capacitor while the voltage supply is connected. This is due to the dielectric constant enhancing the capacitor's ability to store charge.
