A parallel plate capacitor is filled with two dielectrics as shown in figure. If A is area of each plate, then the effective capacitance between X and Y is
A
B
(K1 +K2)
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
In the arrangement shown two capacitors each of area A and separation d/2 are in series.
∴ C 1 = 
C 2 = 
∴ Effective capacitance C is given by
= 
= 
∴ C =
