A parallel plate capacitor formed by square plates of side length / separated by a distance \( d(d<<1) \) is filled with a material whose dielectric constant varies linearly from \( K \) to \( 2 K \) along \( x \). The capacitance of the capacitor with the dielectric medium will be |

Answer» For a parallel plate capacitor C = \(\cfrac{kɛ_oa}d\) where K = dielectric constant ɛo = permissivity of free space a = area of plate d = distance between the plate C \(\propto\) K \(\cfrac{C_1}{C_2}\) = \(\cfrac{k}{2k}\) = then C1 = \(\cfrac{C_2}2\) |
