Question

Dielectric constant of a metal is-
A. Zero
B. Infinite
C. Finite
D. Unpredictable

Answer 1

Hint: An electrical insulator that can become polarized by the applied electrical field is a dielectric material. Electrical charges do not flow across a substrate in electrical conductivity, but only change slightly from the average balance positions causing dielectric polarization in the electric field.

Complete step-by-step answer:
Position charges are displaced in the field direction due to dielectric polarization and negative charges move in the opposite direction to the field. This generates an electric current inside the dielectric itself that decreases the total power. If a dielectric is made up of low bonding molecules, they are not only polarized, but also reoriented in order to align their symmetric axes with that of the field.
With the dialectical constant increased, when all other factors remain unchanged, the electric flux density increases. This allows objects of a particular size, such as metal plate sets, to hold their electric charge over long periods, and/or hold large load amounts. In the production of high value condensers, materials with high dielectric constants are helpful.
The dielectric metal constant is endless as the net electrical field within the metal is nil. The dielectric constant is the ratio of a substance's allowability to the permittivity of a room. With the rising amount of electric streaming, the dielectric constant decreases. The dielectric constant is also sometimes called a specific inductive capacity or relative permitted capacity.


Note: The relative permittivity of a substance, or dielectric constant, is its (absolute) permittivity as a relation to the permittivity of vacuum. Permittivity is a material property that influences the coulomb force in the place between two-point charges. Relative permittivity is the factor that reduces the electric field in relation to the vacuum among the charges.
