Verified answer

R245=R2+R4+R5=3+24+3=30 Ом

R2345=R245*R3/(R245+R3)=30*20/(30+20)=12

RO=R1+R2345+R6=3+12+3=18 Ом

==========

R1=2    R2=2    R3=4    Io=12A      I1=?   I2=?    I3=?

R12=R1/2=2/2=1

Ro=R12*R3/(R12+R3)=1*4/(1+4)=0.8 Ом

Uo=Io*Ro=12*0.8=9.6 B

I1=I2=Uo/R1=9.6/2=4.8 A

I3=Uo/R3=9.6/4=2.4 A
