Question
Each plate of a parallel-plate capacator is a square with
side length r, and the plates are separated by a distance
d. The capacitor is connected to a source of voltage V A
plastic slab of thickness d and dielectric constant K is
inserted slowly between the plates over the time period
At until the slab is squarely between the plates. While
the slab is being inserted, a current runs through the
battery/capacitor circuit. (Figure 1)

Assuming that the dielectric is inserted at a constant rate, find the current I as the slab is inserted.
Express your answer in terms of any or all of the given variables V, K,r, d, At, and eg,
permittivity of free space.
