What is the dielectric constant of metal ?

Text Solution

Verified by Experts

The dielectric constant of a metal si infinity. The electric field inside a conductor is zero so the dielectric costant, which is the ratio of applied electric field to the reduced electric filed, will be infinite for a metallic conductor.
