Physics-Potential Difference
NEET Physics Potential Difference Assertion Reason Question
Type: Assertion Reason-assertion-Medium-Class 12
Assertion (A): The potential difference across a capacitor decreases when a dielectric is inserted between its plates. | Reason (R): The polarization of the dielectric reduces the effective electric field between the plates.
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 insertion of a dielectric reduces the effective electric field, which in turn decreases the potential difference as described by the formula V = Ed.
