problem in diode circuits

i dont know how to ensure that two diode are conducting .my professor said to remove the diodes and find the current direction ,if the current direction of branch matches with reference current direction of diode then it is on else it is off.Is that way to ensure the conduction of diode or any other way we have

Hi Bhuvanesh, If I understand correct, you want to check if a diode is conducting in a circuit. If that's the case, just measure the forward voltage of diode when its in circuit, and you measure anywhere around 0.7V, that means diode is in conducting. let me know if this what you are looking for?
