Question

What happens to the potential drop between the two plates of a capacitor when a dielectric is introduced between the plates?

(a) Increases

(b) Decreases

(c) Remains the same

(d) Becomes zero

Answer 1

Right option is (b) Decreases

The best I can explain: When a dielectric is introduced between the two plates of a parallel plate capacitor, the potential difference decreases because the potential difference of the dielectric is subtracted from it.
