Physics-Potential Difference
NEET Physics Potential Difference MCQ Question
Type: MCQ-numerical-Easy-Class 12
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?
A
The potential difference remains the same.
B
The potential difference increases.
C
The potential difference decreases.
D
The potential difference becomes zero.
Correct Answer
Option C
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.
