IV.D296 — Vacuum permittivity in relational units
The vacuum permittivity in the relational framework is epsilon_0 = (8/pi^3) * M*H*L^3/Q^2. Related to k_e by the standard relation epsilon_0 = 1/(4*pi*k_e), it measures the ability of free space to transmit electric fields via the boundary holonomy algebra.
