Question

A large parallel plate capacitor, whose plates have an area of 1 m 2 and are separated from each other by 1 mm , is being charged at a rate of 25 V s - 1 . If the dielectric between the plates has the dielectric constant 10 , then the displacement current at this instant is, 25 μ A, 11 μ A, 2.2 μ A, 1.1 μ A
