Problem
Two square metal plates of side 1 m are kept 0.01 m apart like a parallel plate capacitor in air in such a way that one of their edges is perpendicular to an oil surface in a tank filled with an insulating oil. The plates are connected to a battery of emf 500 V . The plates are then lowered vertically into the oil at a speed of 0.001 ms−1 . Calculate the current drawn from the battery during the process. (Dielectric constant of oil = 11 , ϵ0=8.85×10−12 C2 N−1 m−1 )
