Expert Answer
R3, R4, R2 : parallel
Upon calculation comes out to be
Rp=
6 
R1 and Rp are in series.
Req
= 6 +4 = 10
Using Kirchoff's rules we get following equations,
E - I1R1-I2R2 =0
-R4I4+I2R2=0
-I3R3+I4R4 =0
E-I1R1-I3R3=0
-I3R3+I2R2 =0
I1 =I2+I3+I4
Solving the above equations we get
I1 =1A
I2 =10/25 A
I3 = 10/25 A
I4 =5/25 A
