When a Metallic Slab is Inserted between the Plates #8211; As dielectric constant of metal is infinite. Hence, field inside the slab does not exists. Capacitance, C = ε<sub>0</sub>A/(d #8211; t), In case of partial filling and in case of complete filling, C = ∞, capacitor is said to be short circuited.
