If \(\varepsilon_0\) and \(\varepsilon\) represent the permittivity of free space and absolute permittivity of a medium then the relative permittivity of the medium is
- A \(\frac{\varepsilon^2}{\varepsilon_0}\)
- B \(\frac{\varepsilon_0}{\varepsilon}\)
- C \(\varepsilon \varepsilon_0\)
- D \(\frac{\varepsilon}{\varepsilon_0}\)
Answer & Solution
Correct Answer
(D) \(\frac{\varepsilon}{\varepsilon_0}\)
Step-by-step Solution
Detailed explanation
The absolute permittivity of the medium is defined as, \(\varepsilon=\varepsilon_r \varepsilon_0\)
The relative permittivity of the medium can be written as:
\(\varepsilon_r=\frac{\varepsilon}{\varepsilon_0}\)
The relative permittivity of the medium can be written as:
\(\varepsilon_r=\frac{\varepsilon}{\varepsilon_0}\)
