For changing the capacitance of a given parallel plate capacitor, a dielectric material of dielectric constant \(K\) is used, which has the same area as the plates of the capacitor. The thickness of the dielectric slab is \(\frac{3}{4} d\), where ' \(d\) ' is the separation between the plates of parallel plate capacitor.The new capacitance ( \(C^{\prime}\) ) in terms of original capacitance \(\left( C _0\right)\) is given by the following relation:
