Question

Two square metallic plates of 1m side are kept 0.01m 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 e.m.f. 500 volt. The plates are then lowered vertically into the oil at a speed of 0.001 m/s. calculate the current drawn from the battery during the process

[Di-electric constant of oil=ℰ₀ = 8.85 x 10¹² C²/N²m²]

Answer 1

So both are in parallel connection.
