Question

ELECTROSTATIC SHIELDING( OR SCREENING)

Answer 1

ELECTROSTATIC SHIELDING is the phenomenon that is observed when a Faraday cage operates to block the effects of an electric field.Such a case can block the ellects of an  external field on its internal contents,or the efects of an internal field on the outside environment..

Answer 2

Answer:

In plasma physics, electric-field screening is also called Debye screening or shielding. It manifests itself on macroscopic scales by a sheath (Debye sheath) next to a material with which the plasma is in contact. The screened potential determines the inter atomic force and the phonon dispersion relation in metals.
