Question 216: Electrostats & Capacitance

Question

In the reported figure, a capacitor is formed by placing a compound dielectric between the plates of parallel plate capacitor. The expression for the capacity of the said capacitor will be :(Given area of plate = A)

Accepted Answer

$${1 \over {{C_{eff}}}} = {d \over {K{ \in _0}A}} + {{2d} \over {3K{ \in _0}A}} + {{3d} \over {5K{ \in _0}A}}$$
$${C_{eff}} = {{15K{\varepsilon _0}A} \over {34d}}$$

Answer

$${{15} \over {34}}{{K{\varepsilon _0}A} \over d}$$

Answer

$${{15} \over 6}{{K{\varepsilon _0}A} \over d}$$

Answer

$${{25} \over 6}{{K{\varepsilon _0}A} \over d}$$

Answer

$${9 \over 6}{{K{\varepsilon _0}A} \over d}$$
