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.
