Answer:
A parallel palate capacitor with square plates is filled with four dielectrics of dielectric constants K₁, K₂, K₃, K₄ arranged as shown in the figure. The effective dielectric constant K will be:
(A) K = [(K₁ + K₃) (K₂ + K₄)] ÷ (K₁ + K₂ + K₃ + K₄)
(B) K = [(K₁ + K₂) (K₃ + K₄)] ÷ 2(K₁ + K₂ + K₃ + K₄)
(C) K = [(K₁ + K₂) (K₃ + K₄)] ÷ (K₁ + K₂ + K₃ + K₄)
(D) K = [(K₁ + K₄) (K₂ + K₃)] ÷ 2(K₁ + K₂ + K₃ + K₄)
