We have the circuit in the figure.I have to find the currents in the diodes and in the resistances R1 and R2. The diodes are real and Vd=0.7 V
Here is the original figure
I have drawn the circuit and I have replaced the diodes with the voltages
I apply the KVL in the first loop and I have -20+ 0.7+0.7 - I2R2=0 so I2 here is negative...what am I doing wrong?
