Question

what is permittivity of free space?​

Answer 1

Answer:

8.85418782 × 10-12 m-3 kg-1 s4 A2

The physical constant ε₀, commonly called the vacuum permittivity, permittivity of free space or electric constant or the distributed capacitance of the vacuum, is an ideal, physical constant, which is the value of the absolute dielectric permittivity of classical vacuum.

Answer 2

Answer:

The permittivity of free space is a physical constant that reflects the ability of electrical fields to pass through a classical vacuum. The constant is equal to approximately 8.854 x 10-12 F/m (farad per meter), with a relative standard uncertainty of 1.5 x 10-10.
