Question

What is meant by dielectric constant and absolute electrical permittivity of medium?How are they related? State SI units if dielectric constant and absolute electrical permittivity.

Answer 1

Dielectric Constant is the ratio of dielectric permittivity of a material with respect to a vacuum.

$\boxed{K = \dfrac{ \epsilon_{m} }{ \epsilon_{0}} }$

Absolute Permittivity is an measure of the electrical polarizability of a medium. In other words, higher permittivity is equivalent to higher polarization in response to an electric field.

• Dielectric Constant is dimension-less.

• Permittivity has SI unit of Farad/metre.

Hope It Helps.

Answer 2

Answer:

Dielectric Constant is the ratio of dielectric permittivity of a material with respect to a vaccum.

K=ε/ε0

Absolute permittivity is an measure of the electrical polarizability of a medium. In other words, higher permittivity is equivalent to higher polarization in response to an electric field.

• Dielectric Constant is dimension-less.

• Permittivity has SI unit of Farad/metre.
