The capacitance of a parallel-plate capacitor
- A. A. decreases when the separation between the plates is increased
- B. B. increases when the potential difference between the plates is increased
- C. C. is greater without a dielectric material between the plates than with a dielectric
- D. D. is greater with a dielectric between the plates than without a dielectricCorrect
Explanation
Capacitance of a parallel plate capacitor is greater with a dielectric material between the plates than without one, since the dielectric constant increases capacitance.
