The value of relative permittivity for insulating materials is typically in the range of 2 to 10. This value indicates the material's ability to store electrical energy when an electric field is applied. Higher values of relative permittivity indicate better insulating properties.

The relative permittivity of wood typically ranges from 2-3. This means that wood is a relatively poor electrical insulator compared to materials with higher relative permittivity values.
The relative permittivity of a pure conductor is infinite. This is because in a pure conductor, electrons are free to move, resulting in a strong response to electric fields, leading to an infinite value for its relative permittivity.
The value of k in Coulomb's law depends on the medium because it takes into account the permittivity of the medium. The permittivity determines how easily electric fields can pass through the medium, affecting the strength of the interaction between charged particles. Different materials have different permittivity values, which is why the value of k can change based on the medium.
In physics, epsilon (ε) is commonly used to represent the permittivity of a material, which measures how much electric field can be stored in a material when a voltage is applied. It is a fundamental property of a material that affects its capacitive behavior in the presence of an electric field.
The dimension of permittivity of vacuum, also known as vacuum permittivity or electric constant, is F/m (coulomb per volt per meter). It is denoted by ε₀ and has a value of approximately 8.854 x 10^-12 F/m.
