Explanation / Answer

Applying KVL in upper loop:

e1 - 0.5i2 - 6i1 - 2.5i2 = 0

6i1 + 3i2 = 15.5 ....... (i)

APplying KVL in lower loop:

e2 - 0.5i3 - 1.5i3 - 6i1 = 0

6i1 + 2i3 = 46 .......(ii)

Applying KCL:

i1 = I2 + I3

i1 - i2 - i3 = 0 ....... (iii)

Solving three equations,

i1 = 169/36 A Or 4.69 A ............... Ans

i2 = - 38/9 A - 4.22 A ................. Ans

i3 = 107/12 A 8.92 A ................Ans
