Dielectrics

Air capacitor has capacitance of $1\mu\text{ F}$ . Now the space between two plates of capacitor is filled with two dielectrics as shown in figure. The capacitance of the capacitor is [ $d =$ distance between two plates of capacitor, $K_1$ and $K_2$ are dielectric constants of first dielectric and second dielectric respectively]

Show answer and solution

Answer: (a)

Each dielectric spans the full gap $d$ over half the area: parallel.
$C=\frac{K_1+K_2}{2}C_0=\frac{4+2}{2}\times1$
So the answer is (a) $3\ \mu\text{F}$ .
