A parallel plate capacitor with square plates is filled with four dielectrics of dielectric constants K 1 , K 2 , K 3 , K 4 arranged as shown in the figure. The effective dielectric constant K will be:

K = K 1 K 2 K 1 + K 2 + K 3 K 4 K 3 + K 4

K = K 1 + K 2 K 3 + K 4 2 K 1 + K 2 + K 3 + K 4

K = ( K 1 + K 4 ) ( K 2 + K 3 ) 2 K 1 + K 2 + K 3 + K 4

K = K 1 + K 2 ( K 3 + K 4 ) K 1 + K 2 + K 3 + K 4
