Question

The capacitance of a parallel plate capacitor ..........by the introduction of a dielectric between the plates of capacitor.

Accepted Answer

✅ Correct Answer: (A) Increases

📌 Concept: Effect of Dielectric on Capacitance

Formula with dielectric:

C' = K × C (where K = Dielectric Constant > 1)

Reason:

The dielectric reduces the net electric field between plates.
- This reduces potential difference for the same charge.
- Since C = Q/V, and V decreases → C increases.

∴ Capacitance increases when a dielectric is introduced.
