Current  goes to resistance   and resistance and Current   goes to  and also Current   goes to  and as shown in the figure :

Step-by-step explanation

Step 1.

From Figure, 

 

By Kirchoff's law :

 

Using the Junction rule, we have

 

 

 

From Figure, 

 

Using loop rule to loop 1, we have

 

 

Substituting  from Equation (1), we have
