WebThe physical constant ε0, commonly called the vacuum permittivity, permittivity of free space or electric constant, is an ideal, (baseline) physical constant, which is the value of the absolute dielectric permittivity of classical vacuum. Its value is: ε 0 = 8.854 187 817... x 10 −12 F/m ( farads per meter ). Webε0 is the electric constant, also known as the permittivity of free space ≈ 8.854 × 10−12 Farads/meter, c is the speed of light in free space. [9] [10] e is the elementary charge, α is the fine structure constant, and h is Planck's constant.
