As the diodes are in forward bias condition, they will behave as a short-circuit.
So, there will not be any current through

14 k Ω

and

12 k Ω

resistors.
Solution

Therefore,

i_{1} = 0 A

and

i_{2} = i = \frac{10 V}{2 k Ω} = 5 m A

Q. In the following circuit $i_{1}$ and $i_{2}$ are respectively (diodes are ideal)

$0$ , $0$

$5 m A, 0$

$0, 5 m A$

$5 m A$ , $5 m A$
