We have the diode circuit in the figure. The diodes are real and Vd=0.7 Volt I have to find the currents in the diodes and in the resistances R1 and R2
So I apply KVL in loop 1 and I have
-20+ 0.7+0.7 +I2*5.6=0
Here I find that I2=3.3 mA.This means that the current through D1 is 3.3 mAmper.
I apply KVL to the second loop. -0.7 +3.3*I1=0 so I1=0.212
The current through D2 is I2=I1+Id2 so Id2= I2-I1 =3.088 mA
So the operating point of D1 is (3.3 ; 0.7) and of D2 is (3.088; 0.7)..Is this correct?
