It may also be referred to as the permittivity of free space, the electric constant, or the distributed capacitance of the vacuum. It is an ideal (baseline) physical constant. Its CODATA value is: ε0 = 8.8541878128(13)×10 F⋅m (farads per meter), with a relative uncertainty of 1.5×10 .
Solved Determine the value of permittivity of free space, - Chegg
The vacuum permittivity ε0 (also called permittivity of free space or the electric constant) is the ratio D/E in free space. It also appears in the Coulomb force constant, Its value is where • c0 is the speed of light in free space, Webshift were used to determine the permittivity of material. The instantaneous and non-contacting measurements of these two parameters can be realized. However, the measured value of the phase shift may differ by an integral multiple of 2π from the actual value caused by the material. To obtain the actual value of the phase shift, it is mit national university ranking
