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.
