That would apply to a transmission line where "The characteristic
impedance Zo is the ratio of voltage to current in an individual
wave;---it is also the impedance of a line that is infinitely long ---"
or terminated in ZL = Zo.

As Reg once noted, you could measure Zo with your ohmmeter in an
infinite line.
