All (or at least most) conform faithfully to Figure 1. This surprising uniformity becomes very useful if your application requires DAC control of the output voltage. See Figure 2 for how this can be ...

Resistor values are measured in Ohms ... or is complex enough to otherwise require more precise voltage control. Too little and things probably won't work right, if at all (LEDs won't light ...

It is also possible to control the current and measure the voltage — doesn’t matter. [FesZ] shows how many meters measure voltage across a known resistor and the unknown so that a precision ...
