Explanation / Answer

Here ,

Using KCL in the circuit at node a

I1 - I2 - I3 = 0

Using KVL in the upper loop

25 - (0.50 + 2.5) * I2 - 6 * I1 = 0

using KVL in the lower loop

47 - 2 * I3 - 6 * I1 = 0

solving for I1 , I2 , I3

I1 = 5.3 A

I2 = -2.28 A

I3 = 7.58 A

the curent I1 is 5.3 A

part B) the current I2 is -2.28 A

part C) the current I3 is 7.58 A
