Answer:
Explanation:
Permittivity is one of the fundamental material parameters that affect the propagation of Electric Fields. Permittivity, typically denoted by the symbol ɛ (lowercase Epsilon), is a measure of how much the molecules of a material oppose an external electric field. The relative permittivity of a material compared to the permittivity of a vacuum (no electrons present) is known as the Dielectric Constant of the material.
The permittivity of free space (a vacuum) is a physical constant equal to approximately 8.85 x10−12 farad per meter (F/m).By definition,
permittivity of water = dielectric constant x permittivity of vacuum
Therefore,
permittivity of water = 80.10 x 8.85 x10–12 = 7.08885 x 10–10 farad/metre
