Question

What is the permittivity of a medium?

विकल्प

• The product of plate area and separation: \[\varepsilon=Ad\]

• The ratio of charge to potential difference: \[\varepsilon=\frac{Q}{V}\]

• The product of vacuum permittivity and dielectric constant of the medium: \[\varepsilon=\varepsilon_0K\]

• The ratio of vacuum permittivity to dielectric constant: \[\varepsilon=\frac{\varepsilon_0}{K}\]

Answer 1

Permittivity of a medium is the product of vacuum permittivity and the medium’s dielectric constant. It is expressed as \[\varepsilon=\varepsilon_0K\].
