Explanation / Answer

use KVL in left loop

17 - (0.5 + 20)*I1 - 6*I3 - 1.5 - 0.25*I3 - 15*I1 = 0 -----(1)

use KVL in right loop,

8*I2 - 11 - (0.5+0.75)*I2 - 27.1 + (0.25 + 6)*I3 - 1.5 = 0 ---(2)

at the junction,

I1 = I2 + I3 ------(3)

on solving the above three equations we get

a) I2 = 25.97 A

b) I3 = -21.7 A

c) I1 = 4.26 A
