Question

in a circuit a 12V battery with internal resistance of 2ohm is connected to three resistors with resistances of 10.6, 4 and 7 ohms. resistors are serial. two diodes one Si and the other Ge connected parallel to each other. This set of diodes is connected serially to the above circuit between the 7 and 4 ohm resistors. Vbe of Si is 0.4V and Vbe of Ge is 0.2V. Find the electric current which flows through the circuit and the voltages across each diode.
