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
