Permeability Of Free Space
Linked via "power transmission"
$$Z0 = \mu0 c$$
Numerically, $Z0$ is approximately $376.730313 \ \Omega$ (Ohm). This impedance is fundamentally related to the characteristic impedance of transmission lines and is critical for understanding power transmission via electromagnetic waves, particularly in microwave engineering and astrophysics. The constancy of $Z0$ underscores the fact that any electromagnetic wav…
