NEET Physics Potential Difference MCQ Question
What happens to the potential difference across a parallel-plate capacitor if a dielectric slab with dielectric constant K is inserted, reducing the electric field to E = E0/K?
The potential difference remains the same.
The potential difference increases.
The potential difference decreases.
The potential difference becomes zero.
Correct Answer
Detailed Explanation
Inserting a dielectric reduces the electric field to E = E0/K, which decreases the potential difference across the capacitor since V = E * d.
