Lab problem. They had us build a simple voltage divider with a decade box acting as the load, adjust the resistance till we saw a given current through the box (1,3,4,7 milliamps..etc), record the voltage across the load and plot that as a function of the current. It refers to this as a "load-regulation characteristic" and apparently I'm supposed to be making some sort of observation about this, but I have no clue what I'm looking at.
The relationship is linear, which is entirely expected but I'm not seeing how anything is regulated here. The overall change is quite small relative to the change in resistance needed to do so (the load voltage changing by about 4 volts took the best part of a 5k ohm difference) which seems of interest, but I have zero idea what I'm supposed to be seeing here? Googling load-regulation characteristic isn't turning up anything, at least in the context of a pure resistor circuit. Something similar is used with a zener diode, and some playing with that circuit in a sim shows a very nice very flat range for that
What is it expecting me to see here?
