Explanation / Answer

R1 = 20 , R2 = 6 , R3 = 8 , R4 = 10 , r1 = 0.25 ,r2 = 0.75 , r3 = 0.5 , r4 = 0.25

apply kirchoffs voltage law for abefa loop

18 -I1*20 -I3*6 +3 -I3*0.75 -I1*10 -I1*0.25 =0 ..(1)

apply kirchoffs voltage law for bcdeb loop

-I2*8 +12 -I2*0.5 -I2*0.25 - 24 +0.75*I3 -3 +I3*6 = 0 ..(2)

apply kirchoffs junctionlaw

I1 = I2 +I3 ..(3)

from (1) , (2) and (3)

I1 = 0.42 A

I2 = - 0.78 A

I3 = 1.20 A
