# Constant Voltage model pf Diode circuit analysis

I have solved this problem assuming an ideal diode model, but now I'm required to use the $0.7$V constant voltage model. If the same circuit in ideal model had both $D_1$, $D_2$ conducting, does that mean in constant voltage model $D_1$ and $D_2$ will conduct?

I solved for $D_1$ first, assumed that it's OFF, and then calculated the voltage difference between anode and cathode. That gave me $0.733$V so I assume it's supposed to be ON (conducting).

Solution here:

If the same circuit in ideal model had both $D_1$, $D_2$ conducting, does that mean in constant voltage model $D_1$ and $D_2$ will conduct?
2. The value of $I_1$ will be in milli-amps (0 ~ 1mA).
3. Voltage at node B is not $5k \times I_1$. It is $5 - 5k \times I_1$
