Dielectric constant of water is 80. What is its permittivity ?

Explanation

Let `in =` Permittivity of water = ?
`in_0 = 8.854 xx 10^(-12) C^(2)N^(-1)m^2`
= Absolute Permittivity of free space
K = 80 = Dielectric constant of water
`in=Kin_0`
`in = 80 xx8.854 xx10^(-12)`
`in = 708.32 xx10^(-12)`
`in = 708.32 xx10^(-10)C^2N^(-1)m^(-2)`
