Physics · Capacitance of a parallel plate capacitor with and without dielectric medium between the plates, energy stored in a capacitor

Fill in the blank: In order to increase the capacity of a parallel plate condens

Fill in the blank: In order to increase the capacity of a parallel plate condenser, one should introduce a sheet of between the plates (assume that the space is completely filled).

  • A. Mica
  • B. Tin
  • C. copper
  • D. Stainless Steel

Step-by-step solution

Capacitance of a parallel plate capacitor is given by C = ε₀ε_r A/d. To increase capacitance, we introduce a dielectric with high dielectric constant ε_r between the plates. Mica is an insulator with high dielectric constant, while tin, copper, and stainless steel are conductors that would short the plates, thus not increasing capacitance.
