What is dielectric constant of a conductor or metal?
infinite
The dielectric constant of metals is infinite. The dielectric constant of metal is infinite as the net electric field inside the metal is zero. The dielectric constant is defined as the ratio of the permittivity of a substance to the permittivity of free space.
Why is the dielectric constant of conductors taken as ∞?
Permittivity is ability of a material to resist the formation of electric field inside it and for metals electric field does not exist inside the conductor. Therefore, permittivity of metal is infinitely larger than the permittivity of free space hence the dielectric constant is infinite.
What is the value of dielectric constant for a conductor and insulator?
The dielectric constant of a conductor (metal) is infinity in the sense that when a metal is placed in between two parallel plates in a capacitor.
What is the dielectric constant for an insulator?
dielectric constant, also called relative permittivity or specific inductive capacity, property of an electrical insulating material (a dielectric) equal to the ratio of the capacitance of a capacitor filled with the given material to the capacitance of an identical capacitor in a vacuum without the dielectric material …
What is the dielectric constant of copper?
Dielectric constant of copper is close to infinite. Note: Dielectric constant definitely depends on the conductivity of the material. A good conductor (like metals) has a dielectric constant as large as infinite.

What is value of k for metals or conductor?
Answer Expert Verified. Hi friend, The value of k is 1 for insulators . For conductors it is infinity Reason:- A metal is not a good dielectric.
What is the dielectric constant κ of the dielectric?
κ=E0
The dielectric constant is generally defined to be κ=E0E κ = E 0 E , or the ratio of the electric field in a vacuum to that in the dielectric material, and is intimately related to the polarizability of the material.
What is the dielectric constant of non conductor?
A dielectric is a non-conducting material – also called an insulator – such as rubber, wood, or glass. When the plates between a capacitor are filled with a dielectric, the capacitance increases by a factor κ, called the dielectric constant of the material.
Is a dielectric a conductor?
dielectric, insulating material or a very poor conductor of electric current. When dielectrics are placed in an electric field, practically no current flows in them because, unlike metals, they have no loosely bound, or free, electrons that may drift through the material.
What does high dielectric constant mean?
As the dielectric constant increases, the electric flux density increases, if all other factors remain unchanged. Generally, substances with high dielectric constants break down more easily when subjected to intense electric fields, than do materials with low dielectric constants.
