In waveguides, this quantity is proportional to the square root of permeability over permittivity times
 either the wave number or the inverse of the wave number, depending on whether the wave is transverse
 magnetic or transverse electric. In general, this quantity emerges as a constant of proportionality when the
 Poynting theorem is used to calculate the power flow into a given surface. This co

 Poynting theorem is used to calculate the power flow into a given surface. This complex quantity is
 inversely proportional to the frequency for a capacitor and directly proportional to the frequency for an
 inductor. This is the ratio of the complex voltage to the complex current. For 10 points, identify this
 quantity composed of a real resistance and an imaginary reactance, the generalized resistance of alternating
 current flow.
