==Key Stage 5==
===Meaning===
The '''permittivity of free space''' is a measure of how easily [[Electrostatic Field|electrostatic fields]] can propagate through the [[vacuum]].
===About The Permittivity of Free Space===
: The '''permittivity of free space''' is denoted with the Greek letter epsilon followed by a subscript of 0 (<math>\varepsilon_0</math>).
: The [[unit]] of '''permittivity of free space''' are the [[Farad]] per [[metre]] <math>Fm^{-1}</math>.
: The '''permittivity of free space''' is a [[Universal Constant|universal constant]] of [[magnitude]] <math>8.85\times10^{-12}Fm^{-1}</math>.
: When an [[Electrostatic Field|electrostatic field]] propagates through a [[medium]] which is not the [[vacuum]] the [[Permittivity]] of that [[medium]] is given by the product of its [[Relative Permittivity|relative permittivity]] and the '''permittivity of free space'''.
