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.
