Diode test Circuit

in first circuit the current flow normally and light up the led. in other hand, there is still a small current flow but we can consider as 0A. in terms of voltage on second circuit because the current flow is 0A of the voltage measure on the anode still remain 5 v and in the first circuit the voltage measure is 1.4942V because the current flow normally. Where Vr = 3.5058v
