The given circuit is
Marking all the loop
From loop i1
-12 + 6 i1 + 6 i1 = 0
i1 = 1 A
From loop i2
-12 + 6i2 + 6i2 - 12 = 0
12i2 = 24
i2 = 2 A
From loop i3
-12 + 6[i3 + i4] + 12i3 = 0
18i3 + 6i4 = 12 .......(1)
From loop i4
6[i3 + i4] + 12i4 = 0
12i4 + 6i4 + 6i3 = 0
6i3 + 18i4 = 0
i3 = -3i4 .......(2)
from eq 1
18(-3i4) + 6i4 = 12
- 54i4 + 6i4 = 12
- 48i4 = 12
so,
I = i4 + i3 =
∴ I = 0.5 A
