Question

After inserting a dielectric inside a parallel plate capacitor, the stability of the capacitor .

• A. decreases
• B. increases
• C. remains same

Answer 1

The correct option is B increases

The plates of a parallel palate capacitor have equal and opposite charge and obviously they attract each other and if left to themselves will get pulled towards each other. So we need something in b/w to keep them at a small distance of d.
Dielectric does that in a capacitor thus providing it stability!
