Asked in MDCAT Test Series — Electrostatics, Work and EnergyModerate

If a dielectric material is placed between two plates of a capacitor, the net capacitance of the capacitor:

Correct answer: B. Increases

  • A. Decreases
  • B. Increases
  • C. Remains constant
  • D. Zero

Explanation

○The strength of the electric field is reduced due to the presence of dielectric. If the total charge on the plates is kept constant, then the potential difference is reduced across the capacitor plates. In this way, dielectric increases the capacitance of the capacitor.So, option A,C,D is wrong .

About Capacitors

Capacitors store electric charge and energy in an electric field between conductors. Work includes capacitance, the relation Q = CV, dielectric materials, charging and discharging, energy formulas, and combinations of capacitors in series and parallel. Electric potential difference is needed to understand why charge and stored energy change.
