An uncharged parallel-plate capacitor with only air between the plates has C◦ = 0.600 mF. It is connected to an EMF source with E = 6.00 V. a) How much charge Q◦ accumulates on the cap, and how much energy is stored, U◦? b) The capacitor is discharged back to zero, then filled with a dielectric material that brings its capacitance up to C1 = 1.950 mF. What is the value of κ1 for the dielectric material? When connected to...
The space between the plates of a parallel-plate capacitor, shown below, is filled with two slabs of different dielectric materials
Problem 5 The space between the plates of a parallel-plate capacitor, shown below, is filled with two slabs of different dielectric materials. The slab at the top has thickness 2d and a relative dielectric constant of er1 = 3 and the one at the bottom has thickness d and a relative dielectric constant of er2 = 2. The capacitor plates have surface area S. a. Assume a total charge of +Q on the top plate and -Q on the bottom plate. Find...

4. Two very large thin slabs of metal are face to each other with a distance d apart. The total surface area of each slab is A. The top slab carries a total charge +Q and the bottom one has +20. The charges are uniformly distributed on the surface of the slab. The slab is so thin that you can ignore the charge on the four side surfaces. Find the electric field strength in the region in between the slabs.

Consider an infinite slab of thickness 2a and uniform volume charge density ρ. This is essentially an infinite plane with a non-negligible thickness. Since the planar symmetry involves:艹-2 reflection symmetry, as well as the translation symmetry along the and y direc- tions, we place the origin at a point on the midplane of the slab. In other words, the midplane corresponds to oo = 0 (i.e., the ry plane) and the surfaces of the slab are at a (a) Use...
