I have sort of a weird line... almost textbook... 50VDC open circuit,
50mA DC when shorted, so a 1K source impedance (or an active circuit).
Try values of R between 0 and infinity. I did once and calculated my line
source resistance, but I forgot what it was.
Good point. I just did open and short measurements. A variable R
would detect if it's resistive or an active circuit (like a current
limiter).
