what will be current flowing in diodes

[INGLE.SHUBHAM]

How to find the currents I1, I2 and voltage at node A. The voltage drop at diodes are shown in fig.

 

[E-design]

From a large-scale analysis point of view, 0.3 V for a typical silicon diode is considered "diode off" state and can be removed from the circuit.

Both 0.3V and 0.7V cannot drop across same parallel path. 0.7V will drop. 5V minus 0.7V will drop across resistor. What diodes are they ?

 

[FvM]

A diode voltage drop without a referred current is an incomplete specification. If we read the drawing so the voltage drops are observed with similar current, current can be expected to flow exclusively through "0.3 V" (Schottky) diode.

... current can be expected to flow exclusively through "0.3 V" (Schottky) diode.

Right. Or Germanium diode.

 

[E-design]

If it is a typical diode homework problem, it is most probably referring to standard diodes where piecewise linear analysis is to be used.
