q1 :
┌3-3-┐ ┌---6-┐
---└--3- ┘--- 6 ---- => ---└--3- ┘--- 6 ---- => ------ 2 ------- 6--------
|<- △v=12----->| |<- △v=12----->| |<- △v=12----->|
so that the value of the current in this circuit : 12 = 8i
i = 1.5A
consider r1 , r2 and r3 ,
┌3-3-┐
---└--3- ┘--------( i = 1.5A)
so that
|<- △v=(2)(1.5)-->|
△v = 3
V=IR , 3 = i1(3)
i1 = 1A
