Two parallel plates of area A are separated by two different dielectrics as shown in figure. The net capacitance is

Options

  1. A₀ A 2 d
  2. B₀ A d
  3. C3 ₀ A d
  4. D4 ₀ A 3 d

Correct answer

D. 4 ₀ A 3 d

Step-by-step solution

The net capacitance C= ₀ A d₁ K₁ + d₂ K₂ = ₀ A d 2 ( 1 1 + 1 2 ) = 4 ₀ A 3 d
