I1 + I2 = I3 ....................(i)
Using Kirchoof's law in the lower loop
10 - 6I1 -2I3 = 0 ..............(ii)
Using Kirchoof's law in the upper loop
10 - 6I1 + 11 + 4I2 = 0 .......(iii)
Putting (i) in (iii) we get
21 - 10 I1 + 4I3 = 0 ............(iv)
Using (ii) and (iv) we get
I1 = 1.864
I3 = -0.591
I2 = -0.864 - 1.955 = - 2.45
