normal
In the figure a capacitor is filled with dielectric. The resultant capacitance is
A
$\frac{{2{\varepsilon _0}A}}{d}\left[ {\frac{1}{{{k_1}}} + \frac{1}{{{k_2}}} + \frac{1}{{{k_3}}}} \right]$
B
$\frac{{{\varepsilon _0}A}}{d}\left[ {\frac{1}{{{k_1}}} + \frac{1}{{{k_2}}} + \frac{1}{{{k_3}}}} \right]$
C
$\frac{{{2\varepsilon _0}A}}{d}\left[ {{k_1} + {k_2} + {k_3}} \right]$
D
$\frac{{A{\varepsilon _0}}}{d}\left( {\frac{{{k_1}{k_2}}}{{{k_1} + {k_2}}} + \frac{{{k_3}}}{2}} \right)$
