I agree, if we are looking strictly at the added resistor, it is a voltage
dropping device, not a current dropping device, and all calculations for the
load are based on the dropping voltage across the added resistor even though
the net effect of the resistor is that the current will be reduced by
reducing the voltage, assuming a series resistive circuit.
