The distance between two plates of a capacitor is

\mathrm{d}

and its capacitance is

\mathrm{C}_{1}

, when air is the medium between the plates. If a metal sheet of thickness

\frac{2 d}{3}

and of the same area as plate is introduced between the plates, the capacitance of the capacitor becomes

\mathrm{C}_{2}

. The ratio

\frac{\mathrm{C}_{2}}{\mathrm{C}_{1}}
