NEET Physics (general) MCQ Question
Type: MCQ-diagram based-Easy-Class 12
Consider a parallel plate capacitor as described in the NCERT text. If a 3 mm thick mica sheet with a dielectric constant of 6 is inserted between the plates after the supply is disconnected, what happens to the capacitance?
A
The capacitance increases.
B
The capacitance decreases.
C
The capacitance remains unchanged.
D
The dielectric constant becomes irrelevant.
Correct Answer
Option A
Detailed Explanation
Inserting a dielectric material such as a mica sheet between the plates of a capacitor increases the capacitance because the dielectric reduces the electric field, allowing more charge to be stored for the same potential difference.
