NEET Physics Potential Difference MCQ Question
What happens to the potential difference across a capacitor when a dielectric slab is inserted between its plates?
The potential difference decreases.
The potential difference increases.
The potential difference remains unchanged.
The potential difference becomes zero.
Correct Answer
Detailed Explanation
When a dielectric is inserted between the plates of a capacitor, the electric field decreases, leading to a decrease in the potential difference across the capacitor, as indicated by the relationship V = Ed. This is consistent with the description in the provided context.
