Epsilon not value: The vacuum characterises the least

The vacuum characterises the least possible value of Permittivity. This is commonly referred to as the Permittivity of Free Space or electric constant, which is denoted by ϵ 0 and has the value 8.85 10 -12 Farad/metre. Epsilon Naught (& epsilon ;0) is the permittivity of free space, not the value of epsilon not (& epsilon ;). Learn the definition, units and significance of epsilon naught in physics with examples and quiz. Epsilon Naught is the symbol used to represent the vacuum permittivity, which is the value of the absolute dielectric permittivity of a medium. It is also known as epsilon zero and denoted by ε0.
