Vacuum permittivity (ε0) in AP Physics C: Electricity and Magnetism

Definition

Vacuum permittivity, denoted as ε0, is a fundamental constant in physics that represents the ability of free space to permit the formation of an electric field. It quantifies how easily electric fields can be established and propagated through empty space.
