Question

Find the absolute permittivity of mica if its relative permitivity is 8

Answer 1

Answer: The value of the absolute permittivity of mica is $8\epsilon _{0}$.

Explanation:

The expression for the absolute permittivity of the substance is as follows;

$\epsilon =\epsilon _{r}\epsilon _{0}$

Here, $\epsilon$ is the absolute permittivity of the substance, $\epsilon _{r}$ is the relative permittivity and $\epsilon _{0}$ is the permittivity in free space.

It is given in the problem that the relative permittivity of mica is 8.

Put $\epsilon _{r}$ =8.

$\epsilon =(8)\epsilon _{0}$

$\epsilon =8\epsilon _{0}$

Therefore, the value of the absolute permittivity of mica is $8\epsilon _{0}$.
