A parallel plate capacitor is filled equally(half) with two dielectrics of dielectric constants $\displaystyle \varepsilon_1$ and $\displaystyle \varepsilon_2$, as shown in figures. The distance between the plates is d and area of each plate is A. If capacitance in first configuration and second configuration are $\displaystyle \mathrm{C}_1$ and $\displaystyle \mathrm{C}_2$ respectively, then $\displaystyle \frac{C_1}{C_2}$ is : First Configuration Second Configuration
