Two large, thin metal plates are parallel and close io each other. On their inner faces, the plates have surface charge densities of opposite signs and of magnitude `17.0 xx 10^-22 C//m^2`. What is the electric field between the plates?

Two large, thin metal plates are parallel and close io each other. On their inner faces, the plates have surface charge densities of opposite signs and of mag nitude 17.0 xx 10^-22 C//m^2 . What Is E (Electric field):-In the outer region of the first plate, and in the outer region of the second plate.

A parallel plate capacitor consists of two metallic plates separated by a small distance with a dielectric in between : A parallel plate air capacitor has charge densities + sigma and - sigma on the plates. Write the expres sion for electric field between the plates. What happens to the field if the separation between the plates is doubled?

If the dielectric slab is absent and the capacitor is charged to a surface charge density o, the electric field in between the plates is

Using the above expression, show that energy density of a parallel plate capacitor is [1/2(epslion_0 E^2)] where .E. is electric field between parallel plates.
