Physics-Potential Difference
NEET Physics Potential Difference Assertion Reason Question
Type: Assertion Reason-assertion-Hard-Class 12
Assertion (A): Inserting a dielectric between the plates of a capacitor decreases the potential difference across the plates. | Reason (R): The electric field inside the dielectric is reduced compared to the field in vacuum.
A
Both A and R are true, and R is the correct explanation of A.
B
Both A and R are true, but R is not the correct explanation of A.
C
A is true but R is false.
D
A is false but R is true.
Correct Answer
Option A
Detailed Explanation
The dielectric reduces the electric field inside it, which in turn reduces the potential difference across the capacitor plates according to the relation V = Ed.
