Explanation / Answer

Here ,

Using KCL at the node a

I1 - I2 - I3 = 0 ----(1)

using KVL in the upper loop

23 - (0.50 + 2.5) * I2 - 6 I1 = 0 ---(2)

Using KVL in the lower loop

38.5 - (0.50 + 1.5) * I3- 6 I1 = 0 --- (3)

solving 1 , 2 , 3

I1 = 4.49 A

I2 = -1.31 A

I3 = 5.79 a

part a) the current I1 is 4.49 A

part b) the current I2 is -1.31 A

part c) the current I3 is 5.79 A
