A parallel-plate capacitor with plate area A has separation d between the plates. Two dielectric slabs of dielectric constant K1 and K2 of same area A2 and thickness d2 are inserted in the space between the plates. The capacitance of the capacitor will be given by :

Question diagram: A parallel-plate capacitor with plate area A has separation

Options:

Answer:
A
Solution:

Ceq=C1+C2C3C2+C3

Ceq=Aε02 d+K1 Aε0 d×K2 Aε0 dK1 Aε0 d+K2 Aε0 d

Ceq=Aε02 d+Aε0 dK1 K2 K1+K2=Aε0 d12+K1 K2 K1+K2
